19-0942; Rev 3; 5/10 ICL761X–ICL764X Single/Dual/Triple/Quad Operational Amplifiers General Description 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 10µA, 100µA, or 1000µA 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. Th.

ICL7621, ICL7641, ICL7642 Data Sheet April 1999 File Number 3403.3 Dual/Quad, Low Power CMOS Operational Amplifiers The ICL761X/762X/764X series is a family of monolithic CMOS operational amplifiers. These devices provide the designer with high performance operation at low supply voltages and selectable quiescent currents. They are an ideal design tool when ultra low input current and low power dissipation are desired. The basic amplifier will operate at supply voltages ranging from ±1V to ±8V, and may be operated from a single Lithium cell. The output swing ranges to within a few millivolts of the supply voltages. The quiescent supply current of these amplifiers is set to 3 different ranges at the factory. Both amps of the dual ICL7621 are set to an IQ of 100µA, while each amplifier of the quad ICL7641 and ICL7642 are set to an IQ of 1mA and 10µA respectively. This results in power consumption as low as 20µW per amplifier. Of particular significance is the extremely low (1pA) input current, input noise current of 0.01pA/√Hz, and 1012Ω input impedance. These features optimize performance in very high source impedance applications. The inputs are internally protected. Outputs are fully protected against short circuits to ground or to either supply. AC performance is excellent, with a slew rate of 1.6V/µs, and unity gain bandwidth of 1MHz at IQ = 1mA. Because of the low power dissipation, junction temperature rise and drift are quite low. Applications utilizing these features may inc.
