WM8190 (8 + 6) Bit Output 14-bit CIS/CCD AFE/Digitiser
Advanced Information, August 1999, Rev 3.0
DESCRIPTION
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 Clamping, Correlated Double Sampling and Programmable Gain and Offset adjust functions. Three multiplexers allow single channel processing. The output from each of these channels is time multiplexed into a single high-speed 14-bit Analogue to Digital Converter. The digital output data is...
