Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of TexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
The TLC8144 integrates the analog signal conditioning required by CCD sensors with a 10-bit ADC and optional pixel-by-pixel image compensation requiring minimal external circuitry and provides a cost effective, sensor-to-digital domain system solution.
Each analog 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 post-processing provides compensation for variations in offset and luminance on a pixel-by-pixel basis.
The flexible output architecture allows 10-bit data to be accessed either on a 10-bit bus or a time-multiplexed 8-bit bus. The TLC8144 can be configured for pixel-by-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 8-bit parallel interface. The TLC8144 is characterized for operation from 0°C to 70°C.
