Scanner Analog Front End 28-Pin SOIC W

The LM9822 is a high performance Analog Front End (AFE) for image sensor processing systems. It performs all the analog and mixed signal functions (correlated double sampling, color specific gain and offset correction, and analog to digital conversion) necessary to digitize the output of a wide variety of CIS and CCD sensors. The LM9822 has a 14 bit 6MHz ADC.
