LM9637 Monochrome CMOS Image Sensor VGA 68 FPS

General Description

Applications

The LM9637 is a high performance, low power, 1/4" VGA CMOS

Active Pixel Sensor capable of capturing monochrome still or

motion images and converting them to a digital data stream.

f Security Camera

f Machine Vision

f Barcode Scanners

f Biometrics

Excellent image quality is achieved by integrating a high perfor-

mance analog signal processor comprising of a high speed 10

bit A/D convertor, fixed pattern noise elimination circuits and a

programmable gain amplifier. The offset and black level can be

automatically adjusted on chip using a full loop black level com-

pensation circuit.

Key Specifications

Total: 488 x 672

Active: 488 x 648

Array Format

Total: 2.93mm x 4.03mm

Active: 2.93mm x 3.89mm

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.
