WM0834, WM0838 Production Data Sept 1996 Rev 2.0 8-Bit ADCs with Serial Interface and Configurable Input Multiplexer Description WM0834 and WM0838 are 8-bit analogue to digital converters (ADC) with configurable 4-input and 8-input multiplexers respectively and a serial I/O interface. Assignment of the multiplexer inputs is configured before each conversion via the serial data input to give single-ended or differential operation for the selected inputs. A mixture of input configurations can be used in the same application. WM0838 also has a pseudo-differential configuration where all 8 inputs can be refered to a common input at an arbitrary voltage. Serial communcation with WM0834/8 is via Data In (DI) and Data Out (DO) wires under the control of clock and chip select inputs.
