MAXIM ICL764X Technical data

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.

Applications
