ICL7611, ICL7612

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, 100

µA, or 10µA, with no external

components. This results in power consumption as low as

20

µW. 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.

AC performance is excellent, with a slew rate of 1.6V/

µs, and

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.
