AD7476 datasheet

Description :

GENERAL DESCRIPTION
The AD7476/AD7477/AD7478 are, respectively, 12-bit, 10-bit, and 8-bit, high speed, low power, successive approximation ADCs. The parts operate from a single 2.35 V to 5.25 V power supply and feature throughput rates up to 1 MSPS. Each part contains a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 6 MHz. The conversion process and data acquisition are controlled using CSand the serial clock, allowing the devices to interface
with microprocessors or DSPs. The input signal is sampled on the falling edge of CSand the conversion is initiated at this point. There are no pipeline delays associated with these parts.
