Product Introduction

Overview

The AD8042AR-REEL, produced by Analog Devices Inc., is a dual 160 MHz rail-to-rail amplifier designed for high-speed and low-power applications. This voltage feedback amplifier operates on single supplies from +3.3 V to +12 V and dual power supplies up to ±6 V. It features true single supply capability with an input voltage range extending 200 mV below the negative rail and within 1 V of the positive rail. The AD8042 is particularly useful in professional video electronics, such as cameras and video switchers, as well as in buffering single-supply, high-speed analog-to-digital converters (ADCs).
