ADA4000-1ARZ-R7

ADA4000-1 is a low cost, precision JFET input operational amplifier. Combining high input impedance, low input bias current, wide bandwidth, fast slew rate, and fast settling time, it is ideal amplifiers for driving analogue-to-digital inputs and buffering digital-to-analogue 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 include electronic instruments, automated test equipment (ATE) amplification, buffering, integrator circuits, instrumentation-quality photodiode amplification, and fast precision filters (including phase-locked loop filters). Application includes reference gain/buffers, level shift/driving, active filters, power line monitoring /control, current/voltage sense or monitoring, data acquisition, sample-and-hold circuits, integrators.
