Dual, Low Power CMOS Operational
Amplifiers
The ICL761X/762X series is a family of monolithic CMOS
operational amplifiers. These devices provide the designer
with high performance operation at low supply voltages and
selectable quiescent currents. They are an ideal design tool
when ultra low input current and low power dissipation are
desired.

The basic amplifier will operate at supply voltages ranging
,
from
±1V
to
±8V,
and may be operated from a single Lithium
L76
cell. The output swing ranges to within a few millivolts of the
supply voltages.

ub-
The quiescent supply current of these amplifiers is set to
100
µ
A at the factory. This results in power consumption as
ct
ual/
low as 200µW per amplifier.
uad,
Of particular significance is the extremely low (1pA) input
current, input noise current of 0.01pA/√Hz, and 10

impedance. These features optimize performance in very
MOS
high source impedance applications.
pera-
The inputs are internally protected. Outputs are fully
nal
protected against short circuits to ground or to either supply.
mpli-
Because of the low power dissipation, junction temperature
rise and drift are quite low. Applications utilizing these

features may include stable instruments, extended life
designs, or high density packages.
