This document describes the features and characteristics of the AD8372 Rev. B product, including dual independent digitally controlled VGA, differential input and output, noise figure, harmonic distortion, gain range, control interface, etc.
The AD8372 from Analog Devices is a dual, digitally controlled variable gain amplifier (VGA) offering precise gain control, low noise figure, and high IP3 for multichannel receiver applications. It features differential inputs and outputs, an 8‑bit SPI interface, and a compact 32‑lead LFCSP package.
The device operates from a single 5 V supply, supports power‑down mode with less than 2 mA consumption, and provides a wide input dynamic range. Detailed specifications, pin descriptions, timing diagrams, and typical performance curves are included in this datasheet.
It is a dual‑channel (two‑channel) variable gain amplifier.
