Overview
The AD8351ARM from Analog Devices Inc. is a low-cost, high-performance differential RF/IF amplifier designed for applications up to 2.2 GHz. Fabricated in Analog Devices' high-speed XFCB process, this amplifier offers high bandwidth, low distortion, and excellent noise characteristics. It is particularly suited for demanding communications transceiver applications, serving as a general-purpose gain block, an ADC driver, and a high-speed data interface driver. The AD8351ARM is available in compact 10-lead MSOP and 16-lead LFCSP packages and operates over a temperature range of −40°C to +85°C.
