1.4MHz, Low Power CMOS Operational
Amplifiers

The ICL761X/762X/764X 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, and 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 cell.

A unique quiescent current programming pin allows setting
of standby current to 1mA, 100µA, or 10µA, with no external
components. This results in power consumption as low as
20µW. The output swing ranges to within a few millivolts of
the supply voltages.

Of particular significance is the extremely low (1pA) input
current, input noise current of 0.01pA/√
impedance. These features optimize performance in very
high source impedance applications.

The inputs are internally protected. Outputs are fully
protected against short circuits to ground or to either supply.

ACperformanceisexcellent,withaslew rate of 1.6V/µs, and
unity gain bandwidth of 1MHz at I

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.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

NOTES:

1. Long term offset voltage stability will be degraded if large input differential voltages are applied for long periods of time.

2. The outputs may be shorted to ground or to either supply, for V
exceeded.

3. θJA is measured with the component mounted on an evaluation PC board in free air.
