Integrated 10-bit Data Acquisition system for Imaging Applications
Description
WM8144-10 integrates the analogue signal conditioning required by CCD sensors with a 10-bit ADC and optional pixel-by-pixel image compensation. WM8144-10 requires minimal external circuitry and provides a cost effective sensor-to-digital domain system solution. Each analogue conditioning channel provides reset level clamp, CDS, fine offset level shifting and gain amplification. The three channels are multiplexed into the ADC. Output from the ADC can either be direct or passed through a digital post-processing function. The postprocessing provides compensation for variations in offset and shading on a pixel-by-pixel basis. The flexible output architecture allows ten-bit data to be accessed either on a ten-bit bus or via a time-multiplexed eight-bit bus. The WM8144-10 can be configured for pixelby-pixel or line-by-line multiplexing operation. Reset level clamp and/or CDS features can be optionally bypassed. Device configuration is either by a simple serial or eightbit parallel interface.
