Description

WM0831 and WM0832 are 8-bit analogue to digital converters (ADC) with serial I/O interfaces, providing a choice of input configurations in 8-pin SO or DIP packages. WM0831 has a differential input, also configurable as a single ended input. A-D conversion results are serially output on Data Out (DO) under the control of clock and chip select inputs. The device has a separate voltage reference input.
