October 2000

The LM9823 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 spe-

cific gain and offset correction, and analog to digital conversion)

necessary to digitize the output of a wide variety of CIS and

CCD sensors. The LM9823 has a 16 bit 6MHz ADC.
