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.
