It operates from a single 2.7 V to 5.25 V power supply and features throughput rates up to 200 kSPS. It 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 by CS and the serial clock, allowing the device to easily interface with microprocessors or DSPs. The input signal is sampled on the falling edge of CS; the conversion is also initiated at this point. The AD7923-EP us...
