The part operates from a single 4.75 V to 5.25 V power supply and features throughput rates up to 1 MSPS. The part contains a low noise, wide bandwidth track-andhold amplifier that can handle input frequencies in excess of 1 MHz. The conversion process and data acquisition are controlled using CS and the serial clock signal, allowing the device to easily interface with microprocessors or DSPs. The input signal is sampled on the falling edge of CS, and conversion is also initiated at this point. There are no pipeline delays associated with the part. The AD7490-EP uses ad.
