UA776
PROGRAMMABLE LOW POWER
SINGLE OPERATIONALAMPLIFIERS
DESCRIPTION
The UA776programmableoperationalamplifier is
characterized by low supply current and low
equivalentinput noisevoltageoverawiderangeof
operating supply voltages.
Coupled with programmable electrical characteristics, it is a versatile amplifier for use in high
accuracy,low power consumptionanalog applications.
Input noise voltage and current, power consumption and input current can be optimizedby a single
resistor or current source that sets the chip quiescent current for nano-watt power consumptionor
for characteristicssimilar to the UA741.
Internalfrequencycompensation,absenceof latch
up, high slew rate and short-circuitprotection assure ease of use in long time integrators, active
filters, and sample and hold circuits.
