WM8144-12 - Integrated 12-bit Data Acquisition System

Key Features

  • WM8144-12 integrates the analogue signal conditioning required by CCD sensors with a 12-bit ADC and optional pixel-by-pixel image compensation. WM8144-12 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.

WM8144-12 Production Data February 1998 Rev. 4.1 Integrated 12-bit Data Acquisition System for Imaging Applications Description Features WM8144-12 integrates the analogue signal conditioning required by CCD sensors with a 12-bit ADC and optional pixel-by-pixel image compensation. WM8144-12 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.
