ICL76XX Series Low Power
CMOS Operational Amplifiers
Features
Description
• Wide Operating Voltage Range
. . . . . . . . . . . .±

±

• High Input Impedance . . . . . . . . . . . . . . . . . . . . . .10

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.
• Programmable Power Consumption . . . .Low as 20
m
W
• Input Current Lower Than BIFIETs. . . . . . . . . . 1pA Typ
• Output Voltage Swing . . . . . . . . . . . . . . . . . . . V+ and V-
The basic amplifier will operate at supply voltages ranging
from
±
1V to
±
8V, and may be operated from a single Lithium
cell.
• Input Common Mode Voltage Range Greater Than
Supply Rails (ICL7612)
Applications
A unique quiescent current programming pin allows setting
of standby current to 1mA, 100
m
A, or 10
m
A, with no external
components. This results in power consumption as low as
20
m
W. The output swing ranges to within a few millivolts of
the supply voltages.
• Portable Instruments
• Telephone Headsets
• Hearing Aid/Microphone Amplifiers
Of particular significance is the extrem
ely
low (1pA) input
current, input noise current of 0.01pA/
Ö
Hz, and 10
12
• Meter Amplifiers
W
input
impedance. These features optimize performance in very
high source impedance applications.
• Medical Instruments
• High Impedance Buffers
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/
m
s, and
unity gain bandwidth of 1MHz at I
Q
= 1mA.
Because of the low power dissipation, junction temperature
rise and drift are quite low. Applications utilizing these fea-
tures may include stable instruments, extended life designs,
or high density packages.
