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. The MP8830 uses ADCs with a subranging architecture to maintain low power consumption at high conversion rates. Our proprietary comparator design achieves a low analog input capacitance and performs an on-chip sample and hold function. The MP8830 uses proprietary high speed DACs to drive the ADC refer...
