ADVANCE INFORMATION

LM9618 Monochrome CMOS Image Sensor VGA 30 FPS

General Description

The LM9618 is a high performance, low power, 1/3” VGA CMOS
Active Pixel Sensor capable of capturing grey-scale 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 conver­tor, fixed pattern noise elimination circuits, a video gain and sep­arate color gain are provided. Furthermore, an integrated
programmable smart timing and control circuit allows the user
maximum flexibility in adjusting integration time, active window
size, gain and frame rate. Various control, timing and power
modes are also provided.

The excellent linear dynamic range of the sensor can be
extended to above 100dB by programming a non linear
response curve that matches the response of the human eye.
