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.
