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

• InternalVoltage Reference Generation

• TTL/CMOS compatible input/output
