The AD7933/AD7934 are 12-bit and 10-bit, high speed, low power, successive approximation (SAR) ADCs. They operate from a single 2.7 V to 5.25 V power supply and feature throughput rates to 1.5 MSPS. The parts feature 4 analog input channels with a channel sequencer to allow a consecutive sequence of channels to be converted on. These parts can accept either single-ended, fully differential, or pseudo-differential analog inputs.
The document describes the AD7933/AD7934 family as 4-channel, 1.5 MSPS successive approximation analog-to-digital converters (ADCs) featuring an on-chip 2.5 V reference and software-configurable inputs. These devices support single-ended, fully differential, and pseudo-differential input modes with no pipeline delays.
