LM9822 LM9822 3 Channel 42-Bit Color Scanner Analog Front End Literature Number: SNOS475 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. Key Specifications Features Applications 6 million pixels/s conversion rate
Digitally programmed gain and offset for red, green and blue
color balancing
