WM8150 Single Channel 12-bit CIS/CCD AFE with 4-bit Wide Output DESCRIPTION The WM8150 is a 12-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 8MSPS. The device includes a complete 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 line-by-line colour processing. The output from this channel is time multiplexed into a high-speed 12-bit Analogue to Digital Converter. The digital output data is available in 4-bit wide multiplexed format. An internal 4-bit DAC is supplied for internal reference level generation.
