WM8141 Description
The WM8141 is a 12-bit analogue front end/digitiser that processes and digitises the analogue output signals from CCDs or Contact Image Sensors (CIS). The device can be operated as either a three channel or a single channel device at pixel sample rates of up to 6MSPS. The device has both external and programmable internal black level reference options for CIS operation.
