LM9810/LM9820

10/12-Bit Image Sensor Processor Analog Front End

General Description

Features

n 6 million pixels/s conversion rate

n Digitally programmed gain and offset for red, green and

blue pixels

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 correction, and analog to digital conversion) nec-

essary to digitize the output of a wide variety of CIS and CCD

sensors. The LM9810 has a 10-bit 6 MHz ADC, and the

LM9820 has a 12-bit 6 MHz ADC. The LM9810 and LM9820

are pin-for-pin and functionally compatible.

n Correlated Double Sampling for lowest noise

n TTL/CMOS input/output compatible

Applications

n Color Flatbed Document Scanners

n Color Sheetfed Scanners

n Multifunction Imaging Products

n Digital Copiers
