MN86157 Datasheet | Panasonic

For munications Equipment Shading Correction LSI Overview 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. It 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 chip is also usable as a stand-alone A/D converter. Pin Assignment Features Choice of correction range (50% or 75%) depending on extent of shading distortion Parallel A/D converter functions Resolution: 7 bits Non-linearity: ± 1/2 LSB Conversion speed: max....
