The MN86157 contains a 7-bit A/D converter for use in correcting, at the bit level, shading distortion for signals from image sensors, optics, and similar sources.
MN86157 uses external RAM to support adaptive correction that responds to changes in distortion patterns. It also uses ROM to provide fixed correction when a white reference plane signal is not available.
The MN86157 chip is also usable as a stand-alone A/D converter.
