Single/Dual/Triple/Quad
Operational Amplifiers
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.
Features
o Pin-for-Pin Second Source
o 1pA Typical Bias Current—4nA (max) at +125°C
o ±1V to ±8V Wide Supply Voltage Range
o Industry-Standard Pinouts
o Programmable Quiescent Currents of 10µA,
100µA, and 1000µA
o Monolithic, Low-Power CMOS Design
