WM8190 (8+6) Bit Output 14-bit CIS/CCD AFE/Digitiser

WM8190 (8+6) Bit Output 14-bit CIS/CCD AFE/Digitiser

The WM8190 is a 14-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 device includes three analogue signal processing channels each of which contains Reset Level Clam.
