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 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 LM9822 has a 14 bit 6MHz ADC.
Features
6 million pixels/s conversion rate
Digitally programmed gain and offset for red, green and blue
color balancing
Correlated Double Sampling for lowest noise from CCD
sensors
Compatible with CCD and CIS type image sensors
Internal Voltage Reference Generation
TTL/CMOS compatible input/output
