The is a 14-bit resolution CMOS Analog-to-digital Converter ADC operates from a single 5V analog power supply and 3 to 5V digital supply. The high-performance low-power ADC has serial interface consists of four digital inputs, frame sync, serial input-output clock, serial data input and a 3-state serial data output. CS\ works as SS\, slave select, SDI, SDO and SCLK form an SPI interface. FS, SDI, SDO and SCLK form a DSP interface. The frame sync signal FS indicates the start of a serial data frame being transferred. When multiple converters connect to one serial port of a DSP, CS\ works as the chip select to allow the host DSP to access the individual converter. CS\ can be tied to ground if only one converter is used. FS must be tied to DVDD if it is not used. When SDI is tied to DVDD, the device is set in hardware default mode after power-on and no software configuration is required. In the simplest case, only three wires are needed to interface with the host.
