The ADC has three control inputs [chip select (CS), the input-output clock, and the address/control input (DATAIN)] designed for communication with the serial port of a host processor or peripheral through a serial 3-state output. In addition to the high-speed converter and versatile control capability, the device has an on-chip 14channel multiplexer that can select any one of 11 inputs or any one of three internal self-test voltag...
