General Description
Features
o Pin-for-Pin Second Source
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 pin-
selectable quiescent currents of 10µA, 100µA, or
1000µA per amplifier, these op amps will operate from
± 1ꢀ to ± ꢁꢀ power supplies, or from single supplies
from 2ꢀ to 16ꢀ. The CMOS outputs swing to within milli-
volts of the supply voltages.
o 1pA Typical Bias Current—4nA (max) at +125°C
o
1ꢀ to ꢁꢀ Vide Supply ꢀoltaꢂe ꢃanꢂe
o Industry-Standard Pinouts
o Proꢂrammable Quiescent Currents of 10µA,
100µA, and 1000µA
o Monolithic, Low-Power CMOS Desiꢂn
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 cur-
rents are critical. A low noise current of 0.01pA√Hz and
an input impedance of 1012Ω ensure optimum perfor-
mance with very high source impedances in such
applications as pH meters and photodiode amplifiers.
