GENERAL DESCRIPTION
The ADA4000-1/ADA4000-2/ADA4000-4 are 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
part an excellent choice for high-side signal conditioning.
Additional applications for the ADA4000-1/ADA4000-2/
ADA4000-4 include electronic instruments, ATE amplification,
buffering, integrator circuits, instrumentation-quality photodiode
amplification, and fast precision filters (including PLL filters).
The parts also include utility functions, such as reference
buffering, level shifting, control I/O interface, power supply
control, and monitoring functions.
