The ICL761X–ICL764X family is a monolithic CMOS op amp that combines ultra-low input current with low-power operation over a wide supply voltage range. It offers pin-selectable quiescent currents of 10µA, 100µA, or 1000µA per amplifier, and can 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 applications such as pH meters and photodiode amplifiers.
The ICL761X–ICL764X family from Maxim Integrated provides ultra‑low input current CMOS op‑amps with selectable quiescent currents and a wide supply voltage range. The devices are offered in single, dual, triple and quad configurations for a variety of precision analog applications.
The datasheet includes detailed electrical characteristics, pin configurations, ordering and package information, as well as example application circuits such as level detectors, integrators and low‑droop sample‑and‑hold circuits.
