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, 100
μ
A, or 10
μ
A, with no external
components. This results in power consumption as low as
20
μ
W. 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
12
Ω
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/
μ
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.
