DESCRIPTION

These circuits are monolithic J-FET input operational

amplifiers incorporating well matched, high voltage

J-FET on the same chip with standardbipolar transis-

tors.

This amplifiers feature low input bias and offset cur-

rents, low input offset voltage and input offset voltage

drift,coupledwith offsetadjustwhichdoesnotdegrade

driftor common-mode rejection.

3 - Non-inverting input

The devicesarealso designedforhigh slew rate, wide

bandwidth,extremelyfastsettlingtime,lowvoltageand

current noise and a low 1/f noise level.
