Backside-illuminated image sensor targets ADAS applications

July 10, 2015 // By Julien Happich
ON Semiconductor is expanding its 1/3-inch 1Mp image sensor portfolio with early sampling of the company's first backside illuminated (BSI) sensor technology for the automotive imaging market.

The innovative new sensor technology is said to deliver 4x better low light signal-to-noise ratio, a 40 percent increase in visible light sensitivity, and greater than 60 percent improvement in near infrared (NIR) performance than its previous offering for advanced driver assistance systems (ADAS).

The AR0136AT 1/3-inch optical format CMOS digital image sensor delivers a 1280x960 resolution from 3.75 micron BSI pixels. The chip supports linear and high dynamic range (HDR) modes, in a single chip HDR solution, with a 120 decibel (dB) dynamic range in HDR mode.

It has an output pixel rate of 74.25 MP/second (maximum), which results in a frame rate of 45 frames per second (fps) at 960p resolution and 60 fps at 720p resolution. It has an operating junction temperature range of -40 to +125°C and will be fully qualified to AEC-Q100. Engineering samples will be available in Q3 of 2015, with mass production planned for early 2016.
