LM9627 Datasheet | National Semiconductor

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 convertor, 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 flexibility in adjusting integration time, active window size, gain and frame rate. Various control, timing and power modes are also provided.
