DESCRIPTION
These circuits are high speed J–FET input quad
operational amplifiers incorporating well matched,
high voltage J–FET and bipolar transistors in a
monolithic integrated circuit.
The devices feature high slew rates, low input bias
and offset currents, and low offset voltage tem-
perature coefficient.
