GENERAL DESCRIPTION
The AD7911/AD79211 are 10-bit and 12-bit, high speed, low power, 2-channel successive approximation ADCs, respectively. The parts operate from a single 2.35 V to 5.25 V power supply and feature throughput rates of up to 250 kSPS. The parts contain a low noise, wide bandwidth track-and-hold amplifier, which can handle input frequencies in excess of 6 MHz.
