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 pin-
selectable 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 milli-
volts 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 cur-
rents are critical. A low noise current of 0.01pA√Hz and
an input impedance of 10
12
Ω
ensure optimum perfor-
mance with very high source impedances in such
applications as pH meters and photodiode amplifiers.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 1:
Long-term offset voltage stability will be degraded if large input differential voltages are applied for long periods of time.
Note 2:
The outputs may be shorted to ground or to either supply for V
SUPP
≤
10V. Care must be taken to insure that the dissipation
rating is not exceeded.
