Each device, with three control inputs [chip select (CS), the input-output clock, and the address input (DATA INPUT)], is designed for communication with the serial port of a host processor or peripheral through a serial 3-state output.
The device allows high-speed data transfers from the host.

The sample-and-hold function is automatic.
At the end of conversion, the end-of-conversion (EOC) output goes high to indicate that conversion is complete.
The converter incorporated in the device features differential high-impedance reference inputs that facilitate ratiometric conversion, scaling, and isolat...
