ON Semiconductor is expanding its 1/3-inch 1 megapixel image sensor portfolio with early sampling of the company's first backside illuminated sensor technology for the automotive imaging market. The sensor technology delivers 4x better low light signal-to-noise ratio, a 40% increase in visible light sensitivity, and greater than 60% improvement in near infrared performance than the current AR0132AT CMOS image sensor for advanced driver assistance systems .
