LM9638 Monochrome CMOS Image Sensor SXGA 18 FPS

General Description

The LM9638 is a high performance, low power, 1/2" SX GA

CMOS Active Pixel Sensor capable of capturing monochrome

still or motion images and converting them to a digital data

stream.

Mega-pixel class 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 cir-

cuits and a programmable gain amplifier. The offset and black

level can be automatically adjusted on chip using a full loop

black level compensation circuit.

Furthermore, a programmable smart timing and control circuit

allowing the user maximum flexibility in adjusting integration

time, active window size, gain, frame rate. Various control, tim-

ing and power modes are also provided.
