DATASHEET ICL7611, ICL7612 FN2919 Rev 9.00 1.4MHz, Low Power CMOS Operational Amplifiers April 26, 2007 The ICL761X series is a family of CMOS operational Features amplifiers. These devices provide the designer with high Wide Operating Voltage Range . 1V to 8V performance operation at low supply voltages and selectable 12 quiescent currents, and are an ideal design tool when ultra High Input Impedance 10 low input current and low power dissipation are desired. Programmable Power Consumption . Low as 20W The basic amplifier will operate at supply voltages ranging Input Current Lower Than BIFETs . 1pA (Typ) from 1V to 8V, and may be operated from a single Output Voltage Swing . V+ and V- Lithium cell. Input Common Mode Voltage Range Greater Than Supply A unique quiescent current programming pin allows setting Rails (ICL7612) of standby current to 1mA, 100A, or 10A, with no external components. This results in power consumption as low as Pb-Free Plus Anneal Available (RoHS Compliant) 20W. The output swing ranges to within a few millivolts of Applications the supply voltages. Portable Instruments Of particular significance is the extremely low (1pA) input 12 current, input noise current of 0.01pA/ Hz, and 10 input Telephone Headsets impedance. These features optimize performance in very Hearing Aid/Microphone Amplifiers high source impedance applications. Meter Amplifiers The inputs are internally protected. Outputs are fully protected against short circuits to ground or to either supply. Medical Instruments AC performance is excellent, with a slew rate of 1.6V/ s, and High Impedance Buffers unity gain bandwidth of 1MHz at I = 1mA. Q 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.
