Overview
The AD8042AR-REEL7, 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 suited for professional video electronics, such as cameras and video switchers, as well as high-speed portable equipment and buffering single-supply, high-speed Analog-to-Digital converters (ADCs).
