GENERAL DESCRIPTION

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.
