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 1012 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 include stable instruments, extended life designs, or high density packages.

CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES: 1. Long term offset voltage stability will be degraded if large input differential voltages are applied for long periods of time. 2. The outputs may be shorted to ground or to either supply, for VSUPPLY 10V. Care must be taken to insure that the dissipation rating is not exceeded. 3. JA is measured with the component mounted on an evaluation PC board in free air. Electrical Specifications VSUPPLY = ±5V, Unless Otherwise Specified SYMBOL VOS TEST CONDITIONS RS 100k TEMP. (oC) 25
