Overview
LM9822 3 Channel 42-Bit Color Scanner Analog Front End May 1999 N LM9822 3 Channel 42-Bit Color Scanner Analog Front End General Description 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.
