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.
