LM9810/20 10/12-Bit Image Sensor Processor Analog Front End

General Description

The LM9810 and LM9820 are high performance Analog Front

Ends (AFEs) for image sensor processing systems. The

LM9810/20 performs all the analog and mixed signal functions

(correlated double sampling, color specific gain and offset cor-

rection, and analog to digital conversion) necessary to digitize

the output of a wide variety of CIS and CCD sensors. The

LM9810 has a 10 bit 6MHz ADC, and the LM9820 has a 12 bit

6MHz ADC. The LM9810 and LM9820 are pin-for-pin and func-

tionally compatible.

Features

• 6 million pixels/s conversion rate

• Digitally programmed gain and offset for red, green and blue

pixels

• Correlated Double Sampling for lowest noise

• TTL/CMOS input/output compatible
