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.
