LM9647 Datasheet | National Semiconductor

Description The LM9647 is a high performance, low power, 1/4" VGA CMOS Active Pixel Sensor capable of capturing color still or motion images and converting them to a digital data stream. Excellent image quality is achieved by integrating a high performance analog signal processor prising of a high speed 10 bit A/D convertor, fixed pattern noise elimination circuits and separate color gain amplifiers . The offset and black level can be automatically adjusted on chip using a full loop black level pensation circuit. 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, timing and power modes are also provided.
