ADA4000-2

• Product introduction

The ADA4000-2 dual, low cost, precision JFET input op amp

The ADA4000-1/ADA4000-2/ADA4000-4 are JFET input op amps with precision, very low bias current, and low power consumption. These amplifiers combine high input impedance, low input bias current, wide bandwidth, fast slew rate, and fast settling time, making them ideal for driving analog-to-digital applicationsconverterInput and buffered digital-to-analog converter output. Input common-mode voltages include positive supply voltages, making these devices an excellent choice for high-end signal conditioning applications.

Other applications for the ADA4000-1/ADA4000-2/ADA4000-4 include electronic instrumentation, automatic test equipment (ATE) amplification, buffering, integrator circuits, instrument-grade photodiode amplification, and fast precision filters (including PLL filters). These devices also include useful functions such as reference buffering, level shifting, control I/O interfaces, power control, and monitoring functions.
