AD7466BRT

GENERAL DESCRIPTION

The AD7466/AD7467/AD7468 are 12-/10-/8-bit, high speed, low power, successive approximation analog-to-digital converters (ADCs), respectively. The parts operate from a single1.6 V to 3.6 V power supply and feature throughput rates up to 200 kSPS with low power dissipation. The parts contain a low noise, wide bandwidth track-and-hold amplifier, which can handle input frequencies in excess of 3 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 CS, and the conversion is also initiated at this point. There are no pipeline delays associated with the part.
