19-0942; Rev 3; 5/10 Single/Dual/Triple/Quad Operational Amplifiers The ICL761X-ICL764X family of monolithic CMOS op amps combine ultra-low input current with low-power operation over a wide supply voltage range. With pinselectable quiescent currents of 10A, 100A, or 1000A per amplifier, these op amps will operate from 1V to 8V power supplies, or from single supplies from 2V to 16V. The CMOS outputs swing to within millivolts of the supply voltages. The ultra-low bias current of 1pA makes this family of op amps ideal for long time constant integrators, picoammeters, low droop rate sample/hold amplifiers and other applications where input bias and offset currents are critical. A low noise current of 0.01pAHz and an input impedance of 1012 ensure optimum performance with very high source impedances in such applications as pH meters and photodiode amplifiers.

The dual and quad amplifiers have fixed quiescent current (IQ) settings. Unity-gain bandwidth and slew-rate increase with increasing quiescent current, as does output sink current capability. The output source current capability is independent of quiescent current. The lowest IQ setting that results in sufficient bandwidth and slew rate should be selected for each specific application. The IQ pin of the single and triple amplifiers controls the quiescent current as follows: IQ = 10A IQ = 100A IQ pin to V+ IQ pin between V- + 0.8V and V+ - 0.8V IQ = 1mA IQ pin to V- Input Offset Nulling The input offset can be nulled by connecting a 25k pot between the OFFSET terminals with the wiper connected to V+. At quiescent currents of 1mA and 100A, the nulling range provided is adequate for all V OS selections. However, with higher values of VOS, and an IQ of 10A, nulling may not be possible. Frequency Compensation All of the ICL7611 and ICL7621 series except the ICL7614 are internally compensated for unity-gain operation. The ICL7614 is externally compensated by a capacitor connected between COMP and OUT pins, with 39pF being greater than unity. The compensation capacitor value may be reduced to increase the bandwidth and slew rate. The ICL7132 is not compensated and does not have frequency compensation pins. Use only at gains 20 at IQ of 1mA; at gains > 10 at IQ of 100A; at gain > 5 at IQ of 10A. Output Loading Considerations Approximately 70% of the amplifier's quiescent current flows in the output stage. The output swing can approach the supply rails for output loads of 1M, 100k, and 10k, using the output stage in a highly linear Class A mode. Crossover distortion is avoided and the voltage gain is maximized in this mode. The output stage, however, can also be operated in Class AB, which supplies higher output currents (see the Typical Operating Characteristics). The voltage gain decreases and the output transfer characteristic is nonlinear during the transition from Class A to Class B operation. The output stage, with a gain that is directly proportional to load impedance, approximates a transconductance amplifier. Approximately the same open-loop gains are obtained at each of the IQ settings if corresponding loads of 10k, 100k, and 1M are used. The maximum output source current is higher than the maximum sink current, and is independent of IQ. Like most amplifiers, there are output loads for which the amplifier stability is not guaranteed. In particular, avoid capacitive loads greater than 100pF; and while on the 1mA IQ setting, avoid loads less than 5k. Since the output stage is a transconductance output, very large (>10F) capacitive loads will create a dominant pole and the output will be stable, even with loads that are less than 5k. Extended Common-Mode Voltage Range (ICL7612/ICL7616) A common-mode voltage range that includes both V+ and V- is often desirable, especially in single-supply operation. The ICL7612/ICL7616 extended commonmode range op amps are designed specifically to meet this need. The ICL7612 input common-mode voltage range (CMVR) extends beyond both power-supply rails when operated with at least 3V total supply and an IQ of 10A or 100A. The ICL7616 CMVR includes the negative supply voltage (or ground when operated with a single supply) at an IQ or 10A or 100A. PC Board Layout Careful PC board layout techniques must be used to take full advantage of the very low bias current of the ICL7611 family. The inputs should be encircled with a low-impedance trace, or guard, that is at the same potential as the inputs. In an inverting amplifier, this is normally ground; in a unity-gain buffer connect the guard to the output. A convenient way of guarding the 8-pin TO-99 version of the ICL7611 is to use a 10-pin circle, with the two extra pads on either side of the input pins to provide space for a guard ring (see Figure 8). Assembled boards should be carefully cleaned, and if a high humidity environment is expected, conformally coated. ______________________________________________________________________________________ 21 ICL761X-ICL764X Detailed Description ICL761X-ICL764X Single/Dual/Triple/Quad Operational Amplifiers Single-Supply Operation Low-Voltage Operation The ICL7611 family will operate from a single 2V to 16V power supply. The common-mode voltage range of the standard amplifier types when operated from a single supply is 1.0V to (V+ - 0.6V) at 10A IQ. At 100A IQ, the CMVR is 1.0V to (V+ - 0.8V), and at 1mA IQ, the CMVR is 1.3V to (V+ - 1.3V). If this CMVR range is insufficient, use the ICL7612, whose CMVR includes both ground and V+, or the ICL7616, whose CMVR includes ground. A convenient way to generate a psuedo-ground at V+/2 is to use one op amp of a quad to buffer a V+/2 voltage from a high-impedance resistive divider. Operation at VSUPP = 1.0V is only guaranteed at IQ = 10A. Output swings to within a few millivolts of the supply rails are achievable for R L (> or =) 1M. Guaranteed input CMVR is 0.6V minimum and typically +0.9V to -0.7V at VSUPP = 1.0V. For applications where greater common-mode range is desirable, see the description of ICL7612 and ICL7616 above. + R + - R1 R R3 VIN + +18V Note that in no case is IQ shown.
