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.
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.
