Product Summary

The AD8021ARZ is a very high performance, high speed voltage feedback amplifier that can be used in 16-bit resolution systems. It is designed to have low voltage and current noise (2.1 nV/√Hz typ and 2.1 pA/√Hz typ) while operating at the lowest quiescent supply current (7 mA @ ±5 V) among today’s high speed, low noise op amps. The applications of the AD8021ARZ include ADC Preamp and Driver, Instrumentation Preamp: Active Filters, Portable Instrumentation, Line Receivers: Precision Instruments, Ultrasound Signal Processing, High Gain Circuits.
