Description
The RT922 device is a rail-to-rail dual BiCMOS
operational amplifier optimized and fully specified
for 3 V and 5 V operation. The device has high
output currents which allow low-load impedances
to be driven.
Very low noise, low distortion, low offset, and a
high output current capability make this device an
excellent choice for aerospace and defense
applications.
The device is stable for capacitive loads up to
500 pF.
