1.4MHz, Low Power CMOS Operational
Ampli铿乪rs
The ICL761X/762X/764X series is a family of monolithic
CMOS operational ampli铿乪rs. 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
卤1V
to
卤8V,
and may be operated from a single
Lithium cell.
A unique quiescent current programming pin allows setting
of standby current to 1mA, 100碌A, or 10碌A, with no external
components. This results in power consumption as low as
20碌W. The output swing ranges to within a few millivolts of
the supply voltages.
Of particular signi铿乧ance is the extremely low (1pA) input
current, input noise current of 0.01pA/鈭欻z, and 10

input
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/碌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
features may include stable instruments, extended life
designs, or high density packages.
