1.4MHz, Low Power CMOS Operational

Amplifiers

The ICL761X series is a family of 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/√Hz, and 10

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

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.
