AD7476 - Analog Devices

AD7476 1-MSPS ADC

The AD7476/AD7477/AD74781 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.
