LM9638
LM9638 is Monochrome CMOS Image Sensor manufactured by National Semiconductor.
Description
The LM9638 is a high performance, low power, 1/2" SX GA CMOS Active Pixel Sensor capable of capturing monochrome still or motion images and converting them to a digital data stream. Mega-pixel class 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 a programmable gain amplifier. 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.
