# 822x-CSI

The AR0822 is an 8-megapixel stacked back-side-illuminated CMOS image sensor that uses a 2.0µm pixel pitched array of 3840 x 2160 pixels, corresponding to a 1/1.8″ (8.81 mm diagonal) optical format. It offers electronic rolling-shutter and global-reset-release readout, feeding up to 4-lane MIPI CSI-2 interface at 350 Mb/s to 2 Gb/s per lane via an 12-bit ADC. In linear mode the device streams native 4 K video at 60 frames per second; high-dynamic-range operation includes two-exposure line-interleaved HDR and three-exposure embedded HDR at up to 30 fps, producing a composite dynamic range of 120 dB, while a single-exposure extended-dynamic-range mode reaches 45 fps. In FullHD mode sensor can stream up to 120fps. Best suitable for: security camera systems, IoT imaging nodes and connected device cameras, vehicle car DVR (dash cam) recorders.
