(1) stresses above these ratings may cause permanent damage. exposure to absolute maximum conditions for extended periods may degrade device reliability. these are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied. (2) input terminals are diode-clamped to the power-supply rails. input signals that can swing more than 0.5v beyond the supply rails should be current limited to 10ma or less. (3) short-circuit to ground, one amplifier per package. this integrated circuit can be damaged by esd. texas instruments recommends that all integrated circuits be handled with appropriate precautions. failure to observe proper handling and installation procedures can cause damage. esd damage can range from subtle performance degradation to complete device failure. precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. package/ordering information (1) product package-lead package designator specified temperature range package marking ordering number transport media, quantity shutdown version opa734 sot23-6 dbv ?40 c to +85 c nsb opa734aidbvt tape and reel, 250 opa734aidbvr tape and reel, 3000 opa734 so-8 d ?40 c to +85 c opa734a opa734aid rails, 100 opa734aidr tape and reel, 2500 opa2734 msop-10 dgs ?40 c to +85 c bgo opa2734aidgst tape and reel, 250 opa2734aidgsr tape and reel, 2500 non-shutdown version opa735 sot23-5 dbv ?40 c to +85 c nsc opa735aidbvt tape and reel, 250 opa735aidbvr tape and reel, 3000 opa735 so-8 d ?40 c to +85 c opa735a opa735aid rails, 100 opa735aidr tape and reel, 2500 OPA2735 so-8 d ?40 c to +85 c OPA2735a OPA2735aid rails, 100 OPA2735aidr tape and reel, 2500 OPA2735 msop-8 dgk ?40 c to +85 c bgn OPA2735aidgkt tape and reel, 250 OPA2735aidgkr tape and reel, 2500 (1) for the most current package and ordering information, see the package option addendum at the end of this document, or see the ti website at www.ti.com.

sbos282b ? december 2003 ? revised february 2005 www.ti.com 8 applications information the opa734 and opa735 series of op amps are unity-gain stable and free from unexpected output phase reversal. they use auto-zeroing techniques to provide low offset voltage and demonstrate very low drift over time and temperature. good layout practice mandates the use of a 0.1 f capacitor placed closely across the supply pins. for lowest offset voltage and precision performance, circuit layout and mechanical conditions should be optimized. avoid temperature gradients that create thermoelectric (seebeck) effects in thermocouple junctions formed from connecting dissimilar conductors. these thermally-generated potentials can be made to cancel by assuring that they are equal on both input terminals: 1. use low thermoelectric-coefficient connections (avoid dissimilar metals). 2. thermally isolate components from power supplies or other heat sources. 3. shield op amp and input circuitry from air currents such as cooling fans. following these guidelines will reduce the likelihood of junctions being at dif ferent temperatures, which can cause thermoelectric voltages of 0.1 v/ c or higher, depending on the materials used. operating voltage the opa734 and opa735 op amp family operates with a power-supply range of +2.7v to +12v ( 1.35v to 6v). supply voltages higher than +13.2v (absolute maximum) can permanently damage the amplifier. parameters that vary over supply voltage or temperature are shown in the typical characteristics section of this data sheet. opa734 enable function the enable/shutdown digital input is referenced to the v? supply voltage of the op amp. a logic high enables the op amp. a valid logic high is defined as > (v?) + 2v. the valid logic high signal can be up to the positive supply, independent of the negative power supply voltage. a valid logic low is defined as < 0.8v above the v? supply pin. if dual or split power supplies are used, be sure that logic input signals are properly referred to the negative supply voltage. the enable pin is connected to internal pull-up circuitry and will enable the device if this pin is left open circuit. the logic input is a cmos input. separate logic inputs are provided for each op amp on the dual version. for battery-operated applications, this feature can be used to greatly reduce the average current and extend battery life. the enable time is 150 s, which includes one full auto-zero cycle required by the amplifier to return to v os accuracy. prior to returning to full accuracy, the amplifier may function properly, but with unspecified offset voltage. disable time is 1.5 s. when disabled, the output assumes a high-impedance state. the disable state allows the opa734 to be operated as a gated amplifier, or to have the output multiplexed onto a common analog output bus. input voltage the input common-mode range extends from (v?) ? 0.1v to (v+) ? 1.5v. for normal operation, the inputs must be limited to this range. the common-mode rejection ratio is only valid within the specified input common-mode range. a lower supply voltage results in lower input common- mode range; therefore, attention to these values must be given when selecting the input bias voltage. for example, when operating on a single 3v power supply, common- mode range is from 0.1v below ground to half the power-supply voltage. normally, input bias current is approximately 100pa; however, input voltages exceeding the power supplies can cause excessive current to flow in or out of the input pins. momentary voltages greater than the power supply can be tolerated if the input current is limited to 10ma. this is easily accomplished with an input resistor, as shown in figure 1. 50 ? opa735 +5v v in v out 10ma max i overload current?limited resistor required if input voltage exceeds supply rails by 0.5v. figure 1. input current protection internal offset correction the opa734 and opa735 series of op amps use an auto-zero topology with a time-continuous 1.6mhz op amp in the signal path. this amplifier is zero-corrected every 100 s using a proprietary technique. upon power-up, the amplifier requires one full auto-zero cycle of approximately 100 s in addition to the start-up time for the bias circuitry to achieve specified v os accuracy. prior to this time, the amplifier may function properly but with unspecified offset voltage.
sbos282b ? december 2003 ? revised february 2005 www.ti.com 9 low-gain (< 20) operation demands that the auto-zero circuitry correct for common-mode rejection errors of the main amplifier. because these errors can be larger than 0.1% of a full-scale input step change, one calibration cycle (100 s) can be required to achieve full accuracy. the term clock feedthrough describes the presence of the clock frequency in the output spectrum. in auto-zeroed op amps, clock feedthrough may result from the settling of the internal sampling capacitor, or from the small amount of charge injection that occurs during the sample-and-hold of the op amp offset voltage. feedthrough can be minimized by keeping the source impedance relatively low (< 1k ? ) and matching the source impedance on both input terminals. if the source resistance is high (> 1k ? ) feedthrough can generally be reduced with a capacitor of 1nf or greater in parallel with the source or feedback resistors. see the circuit application examples. layout guidelines attention to good layout practices is always recom- mended. keep traces short. when possible, use a pcb ground plane with surface-mount components placed as close to the device pins as possible. place a 0.1 f capacitor clo sely across the supply pins. these guidelines should be applied throughout the analog circuit to improve performance and provide benefits such as reducing the electromagnetic-interference (emi) susceptibility. r 1 v ex v out v ref r 1 opa734 r r rr +10v 1nf 1nf figure 2. single op amp bridge amplifier circuit 1/2 OPA2735 r 3 10k ? r 3 10k ? r 1 1k ? 1/2 OPA2735 r 2 1k ? c 4 1nf c 4 1nf r g 10v c 1 (1) 1nf c 2 (1) 10nf c 3 (1) 1nf v ref = 15v 2 4 6 ref102 note: (1) place close to input pins. r r rr g=1+2 r 3 r g figure 3. differential output bridge amplifier
