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

October 2000

LM9810/LM9820

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 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.

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

Applications

Color Flatbed Document Scanners

Color Sheetfed Scanners

Multifunction Imaging Products

Digital Copiers

General Purpose Linear CCD Imaging
