LM9823 3 Channel 48-Bit Color Scanner Analog Front End
General Description
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.
