LM9618 Datasheet | National Semiconductor

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 100d B by programming a non linear response curve that matches the response of the human eye.
