ADA4000-4ARZ Datasheet PDF - ADI

●The ADA4000-4ARZ is a quad JFET input Operational Amplifier features 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 ADA4000-4 is ideal amplifier 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 ADA4000-4 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 device also include utility functions, such as reference buffering, level shifting, control input/output interface, power supply control and monitoring functions.
