ADA4000-1AUJZ-R2 GENERAL DESCRIPTION

The ADA4000-1/ADA4000-2/ADA4000-4 are junction fieldeffect transistor (JFET) input operational amplifiers featuringprecision, very low bias current, and low power. Combininghigh input impedance, low input bias current, wide bandwidth,fast slew rate, and fast settling time, the ADA4000-1/ADA4000-2/ADA4000-4 are ideal amplifiers for driving analog-to-digitalinputs and buffering digital-to-analog converter outputs. Theinput common-mode voltage includes the positive power supply,which makes the device an excellent choice for high-side signalconditioning.Additional applications for the ADA4000-1/ADA4000-2/ADA4000-4 include electronic instruments, automated testequipment (ATE) amplification, buffering, integrator circuits,instrumentation-quality photodiode amplification, and fastprecision filters (including phase-locked loop filters). The devicesalso include utility functions, such as reference buffering, levelshifting, control input/output interface, power supply control,and monitoring functions.
