general description maxim? icl7650/icl7653 are chopper-stabilized amplifiers, ideal for low-level signal processing applica- tions. featuring high performance and versatility, these devices combine low input offset voltage, low input bias current, wide bandwidth, and exceptionally low drift over time and temperature. low offset is achieved through a nulling scheme that provides continuous error correction. a nulling amplifier alternately nulls itself and the main amplifier. the result is an input offset voltage that is held to a minimum over the entire operat- ing temperature range. the icl7650b/icl7653b are exact replacements for intersil? icl7650b/icl7653b. these devices have a 10? max offset voltage, a 0.1?/? max input offset voltage temperature coefficient, and a 20pa max bias current?ll specified over the commercial temperature range. a 14-pin version is available that can be used with either an internal or external clock. the 14-pin version has an output voltage clamp circuit to minimize over- load recovery time. applications condition amplifier precision amplifier instrumentation amplifier thermocouples thermistors strain gauges features icl7650/53 are improved second sources to icl7650b/53b lower supply current: 2ma low offset voltage: 1? no offset voltage trimming needed high-gain cmrr and psrr: 120db min lower offset drift with time and temperature extended common-mode voltage range low dc input bias current: 10pa monolithic, low-power cmos design icl7650/icl7650b/icl7653/icl7653b chopper-stabilized op amps ________________________________________________________________ maxim integrated products 1 icl7650 icl7653 output inverting amplifier with optional clamp input c r c clamp typical operating circuit 19-0960; rev 2; 1/00 pin configurations appear at end of data sheet. ordering information part icl7650 csa icl7650csd icl7650cpa 0? to +70? 0? to +70? 0? to +70? temp. range pin-package 8 so 14 so 8 plastic dip icl7650cpd icl7650ctv icl7650c/d 0? to +70? 0? to +70? 0? to +70? 14 plastic dip 8 to-99 dice icl7650ija icl7650ijd -20? to +85? -20? to +85? 8 cerdip 14 cerdip icl7650mtv icl7650mjd -55? to +125? -55? to +125? 8 cerdip 14 cerdip icl7650b csa icl7650bcsd 0? to +70? 0? to +70? 8 so 14 so icl7650bcpa icl7650bcpd 0? to +70? 0? to +70? 8 plastic dip 14 plastic dip icl7650bctv icl7650bc/d 0? to +70? 0? to +70? 8 to-99 dice icl7653 csa icl7653cpa icl7653ctv 0? to +70? 8 so icl7653b csa icl7653bcpa 0? to +70? 0? to +70? 8 plastic dip 8 to-99 0? to +70? icl7653ija icl7653mtv -55? to +125? -20? to +85? 8 cerdip 8 cerdip 0? to +70? 8 so 8 plastic dip icl7653bctv 0? to +70? 8 to-99 for free samples and the latest literature, visit www.maxim-ic.com or phone 1-800-998-8800. for small orders, phone 1-800-835-8769.

icl7650/icl7650b/icl7653/icl7653b chopper-stabilized op amps 6 _______________________________________________________________________________________ detailed description figure 2 shows the major elements of the icl7650/ icl7653. two amplifiers are illustrated, the main amplifi- er and the nulling amplifier, both of which have offset- null capability. the main amplifier is connected full time from the input to the output. the nulling amplifier, under control of the chopper-frequency oscillator and clock circuit, alternately nulls itself and the main amplifier. this nulling arrangement, which is independent of the output level, operates over the full power-supply and common- mode ranges. the icl7650/icl7653 exhibit an excep- tionally high cmrr, psrr, and a vol . their nulling connections, which are mosfet back gates, have inher- ently high impedance. two external capacitors provide storage for the nulling potentials and the necessary nulling-loop time constants. the icl7650/icl7653 minimize chopper-frequency charge injection at the input terminals by carefully bal- ancing the input switches. feed-forward injection into the compensation capacitor, the main cause of output spikes in this type of circuit, is also minimized. output clamp (icl7650 only) the output clamp reduces the overload recovery time inherent with chopper-stabilized amplifiers. when tied to the summing junction or inverting input pin, a current path between this point and the output occurs just before the output device saturates. this prevents uncontrolled input differential and the consequent charge build-up on the correction-storage capacitors, while causing only a slight reduction in the output swing. intermodulation intermodulation effects can cause problems in older chopper-stabilized amplifier modules. intermodulation occurs since the amplifier has a finite ac gain, and therefore will have a small ac signal at the input. in a chopper-stabilized module, this small ac signal is detected, chopped, and fed into the offset-correction circuit. this results in spurious outputs at the sum and difference frequencies of the chopping and input signal frequencies. other intermodulation effects in chopper- stabilized modules include gain and phase anomalies near the chopping frequency. these effects are substantially reduced in the icl7650/icl7653, which add to the nulling circuit a dynamic current that compensates for the ac signal on the inputs. unlike modules, the icl7650/icl7653 can precisely compensate for the finite ac gain, since both the ac gain rolloff and the intermodulation compensation current are controlled by internal matched capacitors. icl7650 icl7653 output c c r c 0.1 f 0.1 f r2 1m r1 1m icl7650 internal bias ext clk in clk out null c exta c extb cap return b a c p a + - n output +in -in clamp main + - b c int/ext a a a = clk out a ext clk in b c osc figure 1. icl7650 test circuit figure 2. block diagram
icl7650/icl7650b/icl7653/icl7653b chopper-stabilized op amps _______________________________________________________________________________________ 7 nulling capacitor connection separate pins are provided for c retn and clamp in the icl7650. if you do not need the clamp feature, order the icl7653; this device only offers the c retn pin and will produce slightly lower noise and improved ac common-mode rejection. if you need to use the clamp feature, order the icl7650 and connect the external capacitors to v-. to prevent load-current ir drops and other extraneous signals from being injected into the capacitors, use a separate pc board trace to connect the capacitor commons directly to the v- pin. the out- side foil of the capacitors should be connected to the low-impedance side of the null storage circuit, v- or c retn . this will act as an esd voltage shield. clock operation the icl7650? internal oscillator generates a 200hz fre- quency, which is available at the clk out pin. the device can also be operated with an external clock, if desired. an internal pull-up permits the int/ ext pin to be left open for normal operation. however, the internal clock must be disabled and int/ ext must be tied to v- if an external clock is used. an external clock signal may then be applied to the ext clk in pin. the duty cycle of the external clock is not critical at low frequen- cies. however, a 50% to 80% positive duty cycle is pre- ferred for frequencies above 500hz, since the capacitors are charged only when ext clk in is high. this ensures that any transients have time to settle before the capacitors are turned off. the external clock should swing between ground and v+ for power sup- plies up to ?v, and between v+ and (v+ - 6v) for higher supply voltages. to avoid a capacitor imbalance during overload, use a strobe signal. neither capacitor will be charged if a strobe signal is connected to ext clk in so that it is low while the overload signal is being applied to the amplifier. a typical amplifier will drift less than 10?s since the leakage of the capacitor pins is quite low at room temperature. relatively long measurements may be made with little change in offset. applications information device selection in applications that require lowest noise, maxim? icl7652 may be preferred over the icl7650/icl7653. the icl7650/icl7653 offer a higher gain-bandwidth product and lower input bias currents, while the icl7652 reduces noise by using larger input fets. these larger fets, however, increase the leakage at the icl7652? external null pins. therefore, the icl7650/icl7653 can operate to a higher temperature with 0.1? capacitors before the clock ripple (due to leakage at the null capacitor pins) becomes excessive and 1? external capacitors are required. output stage/load driving the icl7650/icl7653 somewhat resemble a transcon- ductance amplifier whose open-loop gain is proportional to load resistance. this behavior is apparent when loads are less than the high-impedance stage (approximately 18k ? for one output circuit). the open-loop gain, for example, will be 17db lower with a 1k ? load than with a 10k ? load. this lower gain is of little consequence if the amplifier is used strictly for dc since the dc gain is typi- cally greater than 120db, even with a 1k ? load. for wideband applications, however, the best frequency response will be achieved with a load resistor of 10k ? or higher. the result will be a smooth 6db per octave response from 0.1hz to 2mhz, with phase shifts of less than 10 in the transition region where the main amplifier takes over from the null amplifier. component selection c exta and c extb , the two required capacitors, have optimum values depending on the clock or chopping frequency. the correct value is 0.1? for the preset internal clock. when using an external clock, scale this component value in proportion to the relationship between the chopping frequency and the nulling time constant. a low-leakage ceramic capacitor may prove suitable for many applications; however, a high-quality film-type capacitor (such as mylar) is preferred. for lowest settling time at initial turn-on, use capacitors with low dielectric absorption (such as polypropylene types). with low-dielectric-absorption capacitors, the icl7650/icl7653 will settle to 1? offset in 100ms, but several seconds may be required if ceramic capacitors are used. thermoelectric effects thermoelectric effects developed in thermocouple junctions of dissimilar materials (metals, alloys, silicon, etc.) ultimately limit precision dc measurements. unless all junctions are at the same temperature, ther- moelectric voltages (typically around 10?/?, but up to hundreds of ?/? for some materials) will be gener- ated. in order to realize the extremely low offset volt- ages that the chopper amplifier can provide, take special precautions to avoid temperature gradients. to eliminate air movement, enclose all components (par- ticularly those caused by power-dissipating elements in the system). minimize power-supply voltages and power dissipation, and use low-thermoelectric-coeffi- cient connections where possible. it is advisable to separate the device surrounding heat-dissipating ele- ments, and to use high-impedance loads.
icl7650/icl7650b/icl7653/icl7653b chopper-stabilized op amps 8 _______________________________________________________________________________________ input guarding low-leakage, high-impedance cmos inputs allow the icl7650/icl7653 to measure high-impedance sources. stray leakage paths can decrease input resistance and increase input currents unless inputs are guarded. boards must be thoroughly cleaned with tce or alcohol and blown dry with compressed air. the board should be coated with epoxy or silicone after cleaning to pre- vent contamination. leakage currents may cause trouble even with properly cleaned and coated boards, particularly since the input pins are adjacent to pins that are at supply potentials. leakage can be significantly reduced by using guard- ing to decrease the voltage difference between inputs and adjacent metal runs. use a 10-lead pin circle, with the leads of the device formed so that the holes adja- cent to the inputs are empty when it is inserted in the board to accomplish input guarding of the 8-pin to-99 package. a conductive ring surrounding the inputs, the ?uard,?is connected to a low-impedance point that is approximately the same voltage as the inputs. the guard then absorbs the leakage current from the high- voltage pins. typical guard connections are shown in figure 3. output inverting amplifier follower input r2 r1 r3* r3* output input use r3 to compensate for large source resistances, or for clamp operation (figure 5). * noninverting amplifier r3* output input r2 r1 note: should be low impedance for optimum guarding. r1 r2 r1 + r2 bottom view board layout for input guarding with to-99 package. 1 v+ v- guard inputs output external capacitors external capacitors 8 7 6 5 4 3 2 figure 3. input guard connection
the 14-pin dip configuration has been specifically designed to ease input guarding. the pins adjacent to the inputs are not used. pin compatibility the icl7653? pinout generally corresponds to that of industry-standard 8-pin devices such as the lm741 or lm101. however, its external null storage capacitors are connected to pins 1 and 8; whereas most op amps leave these pins open or use them for offset null or compensation capacitors. the op05 and op07 op amps can be converted for icl7650/icl7653 operation. this can be accomplished by removing the offset null potentiometer, which is con- nected from pins 1 and 8 to v+, and replacing it with two capacitors connected from pins 1 and 8 to v-. for lm108 devices, the compensation capacitor is replaced by the external nulling capacitors. pin 5 is the output clamp connection on the icl7650/icl7653. by removing any circuit connections from this pin, the lm101/lm748/lm709 devices can undergo a similar conversion. typical applications figure 4 shows the icl7650/icl7653 automatically nulling the offset voltage of a high-speed amplifier. the icl7650/icl7653 continuously monitor the voltage at the amplifier? inverting input, integrate the error, and drive the amplifier? noninverting input to correct for the offset voltage detected at the inverting input. the cir- cuit? dc offset characteristics are determined by the icl7650/icl7653, and its ac performance is deter- mined by the high-speed amplifier. while this circuit continuously and automatically adjusts the amplifier? offset to less than 5?, it does not correct for errors caused by the input bias current, so the value of resis- tor r f should be as low as is practical. this technique can be used with any op amp that is configured as an inverting amplifier. figures 5 and 6 illustrate basic inverting and noninvert- ing amplifier circuits. both figures show an output clamping circuit being used to enhance overload recovery performance. supply voltage (?v max) and output drive capability (10k ? load for full swing) are the only limitations to consider when replacing other op amps with the icl7650/icl7653. use a simple booster circuit to overcome these limitations (figure 7). this enables the full output capabilities of the lm118 (or any other standard device) to be combined with the input capabilities of the icl7650/icl7653. observe the loop gain stability carefully when the feedback network is added, particularly when a slower amplifier such as the lm741 is used. a lower voltage supply is required when mixing the icl7650/icl7653 with circuits that operate at ?5v sup- plies. one approach is to use a highly efficient voltage divider. this is illustrated in figure 8, where the icl7660 voltage converter is used to convert +15v to +7.5v. icl7650/icl7650b/icl7653/icl7653b chopper-stabilized op amps _______________________________________________________________________________________ 9 high- speed amp 0.1 f 47 ? 10k 100k r f icl7650 icl7653 v out r in icl7650 output (r1 || r2) 100k ? for full clamp effect input c r c clamp 0.1 f 0.1 f r2 r1 1k note: r1 || r2 indicates the parallel combination of r1 || r2. figure 4. nulling a high-speed amplifier figure 5. inverting amplifier with optional clamp
