onsemi AR0522 & AR0431 NIR+ CMOS Image Sensors
onsemi AR0522 and AR0431 CMOS image sensors have Near Infra-Red+ (NIR+) technology, which effectively combines high dynamic range (HDR) with enhanced low light performance to enable high-end security and surveillance cameras. onsemi has developed NIR+ technology to increase the Quantum Efficiency (QE) of the sensors in the near-infrared region without sacrificing color fidelity in the visible spectrum. This technique allows security cameras to use fewer IR LEDs on BOM driven at lower voltages and still achieve high-quality images in low light and NIR conditions.
The AR0522 is a 1/2.5-inch 5.1MP image sensor based on a 2.2μm Back Side Illuminated (BSI) pixel technology platform, developed for industrial applications that require high resolution, high-quality video capture in low light conditions. The AR0522 image sensor delivers approximately twice the sensitivity in the near Infra-Red wavelength of the existing AR0521 image sensor.
The AR0431 is a 1/3.2-inch 4MP sensor based on a 2.0μm BSI pixel technology platform. Offering versatile low power modes and a frame rate of up to 120fps, it is perfect for applications where slow-motion video capture is required. Its low operating power makes it ideal for battery-powered security cameras, action/sports cameras, in-car DVRs, and general surveillance cameras.
