GENERAL DESCRIPTION
The AD7927 is a 12-bit, high speed, low power, 8-channel, successive approximation ADC. The part operates from a single 2.7 V to 5.25 V power supply and features throughput rates up to 200 k SPS. The part contains a low noise, wide bandwidth track-and-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 device to easily interface...
