GENERAL DESCRIPTION

The MP8830 is a simultaneous sampling 1.25 MSPS triple 10-bit A/D Converter. It provides pixel-to-pixel correction of CCD or other inputs by updating gain and offset parameters supplied from an external correction memory. Each ADC has a 9-bit DAC driving its positive reference voltage and a 6-bit DAC driving its negative reference to independently adjust the gain and offset of each channel.
