AD7904BRUZ-REEL

Product Summary

The AD7904BRUZ-REEL is respectively, 8-bit, high speed, low power, 4-channel, successive-approximation ADC. The AD7904BRUZ-REEL operates from a single 2.7 V to 5.25 V power supply and feature throughput rates up to 1 MSPS. It contains a low noise, wide bandwidth track/hold amplifier that can handle input frequencies in excess of 8 MHz. The conversion process and data acquisition are controlled using CS and the serial clock signal, allowing the AD7904BRUZ-REEL to easily interface with microprocessors or DSPs. The input signal is sampled on the falling edge of CS and conversion is also initiated at this point. There are no pipeline delays associated with the part.
