Product Summary

The WM8198SCDS is a 16-bit analogue front end/digitiser IC which processes and digitises the analogue output signals from CCD sensors or Contact Image Sensors (CIS) at pixel sample rates of up to 6MSPS. The WM8198SCDS includes three analogue signal processing channels each of which contains Reset Level Clamping, Correlated Double Sampling and Programmable Gain and Offset adjust functions. Three multiplexers of the WM8198SCDS allow single channel processing. The output from each of these channels is time multiplexed into a single high-speed 16-bit Analogue to Digital Converter. The digital output data is available in 8 or 4-bit wide multiplexed format.
