General Description

The WM8255 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 12 MSPS.

The device includes a plete signal processing channel containing Reset Level Clamping, Correlated Double Sampling, Programmable Gain and Offset adjust functions.

Internal multiplexers allow fast switching of offset and gain for line-by-line colour processing.
