Overview
The AD8367ARUZ-RL7 is a high-performance variable gain amplifier produced by Analog Devices Inc. This component is designed for use in a wide range of applications requiring precise gain control from low frequencies up to several hundred megahertz. The AD8367 utilizes Analog Devices’ patented X-AMP® architecture, which ensures a broad-range analog variable gain of -2.5dB to +42.5dB. It features a 3dB cut-off frequency of 500MHz, making it suitable for high-frequency applications. The amplifier operates in a single-supply range from 2.7V to 5.5V and is packaged in a 14-lead TSSOP package, with an operating temperature range from -40°C to 85°C.
