Datasheet
AD8331/AD8332 are single- and dual-channel ultralow noise, linear-in-dB, variable gain amplifiers. Although optimized for ultrasound systems, they are usable as low noise variable gain amplifiers. They provide up to 43.5 dB of linear variable gain with low output-referred noise and high input impedance matching.
Datasheet
This document describes the features of Analog Devices' AD8331/AD8332/AD8334 series ultralow noise variable gain amplifiers (VGAs) with preamplifier. The features include ultralow noise, wide gain range, low power consumption, and applications such as ultrasound and sonar time-gain controls, high performance automatic gain control systems, and I/Q signal processing.
