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.
