Product Introduction

Overview

The AD8370AREZ-RL7, produced by Analog Devices Inc., is a high-performance, digitally controlled variable gain amplifier (VGA). This component is designed for use at intermediate frequencies (IF) within communication infrastructure equipment. It offers precision gain control, high third-order intercept point (IP3), and a low noise figure, making it an ideal choice for modern receiver designs. The AD8370 operates on a single 3 V to 5 V supply and is packaged in a 16-lead thin shrunk small outline (TSSOP) package, ensuring space efficiency and reliability over a temperature range of –40°C to +85°C.
