ADA4000-4 Quad, Low Cost, Precision JFET Input Operational Amplifier
The ADA4000-1 / ADA4000-2 / ADA4000-4 are junction field
effect transistor (JFET) input operational amplifiers featuring
precision, very low bias current, and low power. Combining
high 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-digital
inputs and buffering digital-to-analog converter outputs. The
input common-mode voltage includes the positive power supply,
which makes the device an excellent choice for high-side signal
conditioning.
Additional applications for the ADA4000-1 / ADA4000-2 / ADA4000-4 include electronic instruments, automated test
equipment (ATE) amplification, buffering, integrator circuits,
instrumentation-quality photodiode amplification, and fast
precision filters (including phase-locked loop filters). The devices
also include utility functions, such as reference buffering, level
shifting, control input/output interface, power supply control,
and monitoring functions.
