ICL7612BCPA Datasheet

Operational Amplifiers - Op Amps


The ICL761X–ICL764X ( ICL7612BCPA ) 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. 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 0.01pA√Hz and an input impedance of 1012Ω ensure optimum performance with very high source impedances in such applications as pH meters and photodiode amplifiers.
