WM8148, 12-bit/12MSPS CCD/CIS Analogue Front End/Digitiser

WM8148 12-bit/12MSPS CCD/CIS Analogue Front End/Digitiser Production Data, April 1999, Rev 4.0 .
The WM8148 is a 12-bit, 12MSPS analogue front end/ digitiser IC, which interfaces to colour or monochrome linear array CCDs or contact image sensors (.

Features

* reset level clamping, correlated double sampling (CDS), offset correction and programmable gain amplification (PGA). The output signal from each channel is then multiplexed into a high performance 12-bit analogue to digital converter (ADC). The reset level clamp and/or CDS functions can be selected

Applications

* Flatbed scanners Document scanners Multi-function peripherals (MFPs) Colour copiers Character recognition systems Linear array CCDs Contact image sensors (CIS) BLOCK DIAGRAM RLC (2) MCLK VSMP (5) (7) AVDD 1- 4 (41,28,27,3) DVDD1-
