LM9647 Datasheet LM9647 Color CMOS Image Sensor

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM9647 Color CMOS Image Sensor VGA 68 FPS ADVANCE INFORMATION May 2002 LM9647 Color CMOS Image Sensor VGA 68.

General Description

The LM9647 is a high performance, low power, 1/4" VGA CMOS Active Pixel Sensor capable of capturing color still or motion images and converting them to a digital data stream.

Excellent image quality is achieved by integrating a high performance analog signal processor comprising of a high speed 10 bit A/D convertor, fixed pattern noise elimination circuits and separate color gain amplifiers .

The offset and black level can be automatically adjusted on chip using a full loop black level compensation circuit.
