General Description

The WM8259 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 3MSPS.

The device has two selectable video input pins and one plete analogue 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 lineby-line colour processing.
