LM9627 Color CMOS Image Sensor VGA 30 FPS

March 2001

LM9627 Color CMOS Image Sensor VGA 30 FPS

General Description

The LM9627 is a high performance, low power, third inch VGA

CMOS Active Pixel Sensor capable of capturing color digital still

or motion images and converting them to a digital data stream.

In addition to the active pixel array, an on-chip 12 bit A/D conver-

tor, fixed pattern noise elimination circuits and a video gain

amplifier is provided. Furthermore, an integrated programmable

smart timing and control circuit allows the user maximum flexibil-

ity in adjusting integration time, active window size, gain and

frame rate. Various control, timing and power modes are also

provided.
