DESCRIPTION
These circuits are monolithic J-FET input operational
amplifiers incorporating well matched, high voltage
J-FET on the same chip with standard bipolar transis-
tors.
This amplifiers feature low input bias and offset cur-
rents, low input offset voltage and input offset voltage
drift,coupledwith offsetadjust which doesnot degrade
drift or common-mode rejection.
The devices are also designed for high slew rate, wide
bandwidth,extremelyfastsettlingtime, lowvoltageand
current noise and a low 1/f noise level.
