LT1803/LT1804/LT1805 Single/Dual/Quad 100V/s, 85MHz, Rail-to-Rail Input and Output Op Amps DESCRIPTIO
The LT(R)1803/LT1804/LT1805 are single/dual/quad, low power, high speed rail-to-rail input and output operational amplifiers with excellent DC performance. The LT1803/ LT1804/LT1805 feature reduced supply current, lower input offset voltage, lower input bias current and higher DC gain than other devices with comparable bandwidth and slew rate. Typically, the LT1803/LT1804/LT1805 have an input offset voltage of 350V, an input bias current of 125nA and an open-loop gain of 60V/mV. The LT1803/LT1804/LT1805 have an input range that includes both supply rails and an output that swings within 20mV of either supply rail to maximize the signal dynamic range in low supply applications. The LT1803/LT1804/LT1805 are specified at 3V, 5V and 5V supplies and typically maintain their performance for supplies from 2.3V to 12.6V. The inputs can be driven beyond the supplies without damage or phase reversal of the output. The LT1803 is available in the 8-pin SO package with the standard op amp pinout and in the 5-pin SOT-23 package. The LT1804 is available in 8-pin DFN and SO packages with the standard op amp pinouts. The LT1805 features the standard quad op amp configuration and is available in a 14-pin plastic SO package.

Note 1: Absolute Maximium Ratings are those values beyond which the life of the device may be impaired. Note 2: The inputs are protected by back-to-back diodes and by ESD diodes to supply rails. If the differential input voltage exceeds 1.4V, or if an input is driven beyond the supply rails, the input current should be limited to less than 10mA. This parameter is not tested; however it is guaranteed by characterization. Note 3: A heat sink may be required to keep the junction temperature below the absolute maximum rating when the output is shorted indefinitely. Note 4: The LT1803C/LT1803I, LT1804C/LT1804I and LT1805C/LT1805I are guaranteed functional over the temperature range of -40C and 85C. Note 5: The LT1803C/LT1804C/LT1805C are guaranteed to meet specified performance from 0C to 70C. The LT1803C/LT1804C/LT1805C are designed, characterized and expected to meet specified performance from
-40C to 85C but are not tested or QA sampled at these temperatures. The LT1803I/LT1804I/LT1805I are guaranteed to meet specified performance from -40C to 85C. Note 6: Minimum supply voltage is guaranteed by power supply rejection ratio test. Note 7: Output voltage swings are measured between the output and power supply rails. Note 8: This parameter is not 100% tested. Note 9: Matching parameters are the difference between amplifiers A and D and between B and C on the LT1805; between the two amplifiers on the LT1804. Note 10: Full power bandwidth is based on slew rate: FPBW = SR/2VP

Circuit Description
The LT1803/LT1804/LT1805 have input and output signal ranges from the negative power supply to the positive power supply. Figure 1 depicts a simplified schematic of one amplifier. The input stage is comprised of two differential amplifiers, a PNP stage Q1/Q2 and an NPN stage Q3/ Q4 that are active over the different ranges of the common mode input voltage. The PNP differential pair is active between the negative supply and approximately 1.3V below the positive supply. As the input voltage moves toward the positive supply, the transistor Q5 will steer the tail current I1 to the current mirror Q6/Q7 activating the NPN differential pair. The PNP pair becomes inactive for the rest of the input common mode range up to the positive supply. Also at the input stage, devices Q18 and Q19 act to cancel the bias current of the PNP input pair. When Q1 and Q2 are active, the current in Q16 is controlled to be the same as the current in Q1 and Q2; therefore, the base current of Q16 is nominally equal to the base current of the input devices. The base current of Q16 is then mirrored by devices Q17 through Q19 to cancel the base current of the input devices Q1 and Q2. A pair of complementary common emitter stages Q14/ Q15 that enable the output to swing from rail-to-rail constructs the output stage. The capacitors C1 and C2 form the local feedback loops that lower the output impedance at high frequency. The LT1803/LT1804/LT1805 are fabricated on Linear Technology's proprietary high speed complementary bipolar process.

Power Dissipation There is a need to ensure that the die's junction temperature does not exceed 150C. Junction temperature TJ is calculated from the ambient temperature TA, power dissipation PD and thermal resistance JA: TJ = TA + (PD * JA) The power dissipated in the IC is a function of the supply voltage, amplifier current, output voltage and output current. For a given supply voltage, the worst-case power dissipation, PDMAX, occurs when the output current and voltage drop in the amplifier product is maximized. For example, if the amplifier is sourcing a constant current then the PDMAX occurs when the output voltage is at about VS-. On the other hand, for a given load resistance to ground, the PDMAX will occur when the output voltage is at half of either supply voltage. PDMAX for a given resistance to ground is given by: PDMAX = (VS+ - VS-) ISMAX + (VS/2)2/RL Example: An LT1804 in an SO-8 package operating on 5V supplies and driving a 100 load to ground, the PDMAX per amplifier is given by: PDMAX = (10 * 3.25mA) + (2.5)2/100 = 0.0425 + 0.0625 = 0.095W ISMAX is approximated for a typical part from the Supply Currrent vs Supply Voltage graph.

If both amplifiers are loaded simultaneously, then the total power dissipation is 0.19W. The maximum ambient temperature that the part is allowed to operate is: TA = TJ - (PDMAX * 190C/W) = 150C - (0.190W * 190C/W) = 113.9C Similar calculations can be carried out for specific packages and conditions. Also worth noting, the DD package includes a low JA underside metal which is internally connected to VS-. If the underside metal is properly soldered to a PCB, the JA of the part will be close to 50C/W. This JA is significantly less than leaving the underside metal unattached and can be useful for certain applications. Input Offset Voltage The input offset voltage will change greatly based upon which input stage is active. The PNP input stage is active from the negative supply voltage to about 1.3V below the positive supply rail, then the NPN input stage is activated for the remaining input range up to the positive supply rail during which the PNP stage remains inactive.

voltage is typically less than 1000V in the range the PNP input stage is active. Input Bias Current The LT1803/LT1804/LT1805 employ a patent-pending technique to reduce the input bias current to less than 1A for the input common mode voltage range of 0.2V above the negative supply rail to 1.75V below the positive rail. The low input offset voltage and low input bias current provide precision performance in high source impedance applications. Output The LT1803/LT1804/LT1805 can deliver a large output current, so the short-circuit current limit is set around 50mA to prevent damage to the device. Attention must be paid to keep the junction temperature of the IC below the absolute maximum rating of 150C (refer to the Power Dissipation section) when the output is continuously short circuited. The output of the amplifier has reverse-biased diodes connected to each supply. If the output is forced beyond either supply, unlimited current will flow through these diodes. If the current is transient and limited to less than 100mA and the total supply voltage is less than
180345f
LT1803/LT1804/LT1805
APPLICATIO S I FOR ATIO
12.6V, the absolute maximum rating, no damage will occur to the device. Overdrive Protection When the input voltage exceeds the power supplies, two pairs of crossing diodes D1 through D4 will prevent the output from reversing polarity. If the input voltage exceeds either power supply by 700mV, diode D1/D2 or D3/D4 will turn on to keep the output at the proper polarity. For the phase reversal protection to perform properly, the input current must be limited to less than 10mA. If the amplifier is severely overdriven, an external resistor should be used to limit the overdrive current. The LT1803/LT1804/LT1805's input stages are also protected against a large differential input voltage of 1.4V or higher by a pair of back-to-back diodes D5 through D8 to prevent the emitter-base breakdown of the input transistors. The current in these diodes should be limited to less than 10mA when they are active. The worst-case differential input voltage usually occurs when the input is driven while the output is shorted to ground in a unity gain configuration. In addition, the amplifier is protected against ESD strikes up to 3kV on all pins by a pair of protection diodes on each pin that is connected to the power supplies as shown in Figure 1.
U
Capacitive Load The LT1803/LT1804/LT1805 are optimized for wide bandwidth, low power and precision applications. They can drive a capacitive load of about 20pF in a unity-gain configuration, and more for higher gain. When driving a larger capacitive load, a resistor of 10 to 50 should be connected between the output and the capacitive load to avoid ringing or oscillation. The feedback should still be taken from the output so that the resistor will isolate the capacitive load to ensure stability. Graphs on capacitive load indicate the transient response of the amplifier when driving a capacitive load with a specified resistor. Feedback Components When feedback resistors are used to set up gain, care must be taken to ensure that the pole formed by the feedback resistors and the total capacitance at the inverting input does not degrade stability. For instance, the LT1803/ LT1804/LT1805 in a noninverting gain of 2 setup with two 5k resistors and a capacitance of 5pF (part plus PC board) will probably oscillate. The pole formed at 12.7MHz, reduces phase margin by about 58 degrees when the crossover frequency of the amplifier is around 20MHz. A capacitor of 5pF or higher connected across the feedback resistor will eliminate any ringing or oscillation.
