Overview
The AD8350ARM20, produced by Analog Devices Inc., is a high-performance fully-differential amplifier designed for use in RF and IF circuits up to 1000 MHz. This amplifier is particularly suited for demanding communications transceiver applications, offering exceptional linearity, high dynamic range, and increased common-mode rejection. It is available in two gain versions: 15 dB (AD8350-15) and 20 dB (AD8350-20), and can operate from a single supply voltage ranging from 5 V to 10 V. The device is fabricated using Analog Devices’ proprietary high-speed complementary bipolar process and is available in 8-lead SOIC and microSOIC packages.
