AD7934BRU Datasheet PDF - ADI

●GENERAL DESCRIPTION

●The AD7933/AD7934 are 10-bit and 12-bit, high speed, low power, successive approximation (SAR) analog-to-digital converters (ADCs). The parts operate from a single 2.7 V to 5.25 V power supply and feature throughput rates up to 1.5 MSPS. The parts contain a low noise, wide bandwidth, differential track and-hold amplifier that handles input frequencies up to 50 MHz.
