Overview
The AD8042ARZ, 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 can operate on single supplies of +3 V, +5 V, or +12 V, as well as dual 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 AD8042ARZ is particularly suited for professional video electronics, high-speed portable equipment, and buffering single-supply, high-speed analog-to-digital converters (ADCs) due to its low distortion and fast settling times.
