WM8146 12-bit (8+4-bit) Linear Sensor Image Processor Product Preview, January 2000 Rev 1.1 DESCRIPTION The WM8146 is a 12-bit analogue front end/digitiser IC, which processes and digitises the analogue output signals from linear CCD sensors at pixel sample rates of up to 6MSPS. The device includes three analogue signal processing channels each of which contains Reset Level Clamping, Correlated Double Sampling and Programmable Gain and Offset adjust functions. The output from each of these channels is time multiplexed into a single high-speed 12-bit Analogue to Digital Converter. The digital output data is available in 8+4-bit wide multiplexed format, with no missing codes.
