DESCRIPTION
The UA776 programmable operational amplifier is
characterized by low supply current and low
equivalent input noise voltage over a wide range of
operating supply voltages.
Coupled with programmable electrical charac-
teristics, it is a versatile amplifier for use in high
accuracy, low power consumption analog applica-
tions.
Input noise voltage and current, power consump-
tion and input current can be optimized by a single
resistor or current source that sets the chip quies-
cent current for nano-watt power consumption or
for characteristics similar to the UA741.
Internal frequency compensation,absence of latch
up, high slew rate and short-circuit protection as-
sure ease of use in long time integrators, active
filters, and sample and hold circuits.
