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 to 1.5 MSPS. The parts contain a low noise, wide bandwidth, differential trackand-hold amplifier that handles input frequencies up to 50 MHz. The AD7933/AD7934 feature four analog input channels with a channel sequencer that allow a preprogrammed selection of channels to be sequentially converted. These parts can accept either single-ended, fully differential, or pseudo differential analog inputs.
