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

General Description

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 (CIS).

Key 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 or bypassed depending on the.

WM8148 12-bit/12MSPS CCD/CIS Analogue Front End/Digitiser Production Data, April 1999, Rev 4.0 DESCRIPTION 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 (CIS). The device includes all the signal conditioning circuitry required to process the analogue signals from the CCD or CIS prior to the internal ADC. Three signal-processing channels are included in the device. Each channel 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).
