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 ca- pacitance and performs an on-chip sample and hold function. The MP8830 uses proprietary high speed DACs to drive the ADC references which allows reference adjustment on every conversion at a 1.25 MHz rate. An internal clamp is available for DC restoration of AIN black level. The MP8830 operates from a single 5 V supply and an exter- nal 1 V reference, and consumes only 500mW of power (typ). Specified for operation over the temperature range 0 to 60 °C, the MP8830 is available in a 64 lead Plastic Quad Flat Pack (PQFP) package.
