Product Summary

The AD7934BRU is a 10-bit, high speed, low power, successive approximation (SAR) ADC. The device operates from a single 2.7 V to 5.25 V power supply and feature throughput rates to 1.5 MSPS. The AD7934BRU contains a low noise, wide bandwidth, differential track-and-hold amplifier that can handle input frequencies up to 20 MHz. The AD7934BRU features 4 analog input channels with a channel sequencer to allow a consecutive sequence of channels to be converted on. It can accept either single-ended, fully differential, or pseudo-differential analog inputs.
