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.

• Output Voltage Swing . . . . . . . . . . . . . . . . . . . V+ and V-
• Input Common Mode Voltage Range Greater Than Supply
Rails (ICL7612)
The basic amplifier will operate at supply voltages ranging
from ±1V to ±8V, and may be operated from a single
Lithium cell.
Applications
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.
• Portable Instruments
• Telephone Headsets
• Hearing Aid/Microphone Amplifiers
• Meter Amplifiers
Of particular significance is the extremely low (1pA) input
current, input noise current of 0.01pA/√Hz, and 10 Ω input
impedance. These features optimize performance in very
high source impedance applications.
• Medical Instruments
• High Impedance Buffers

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

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.
