Our infrared digital readout integrated circuits (ROICs) cover a wide range of specifications, including resolutions of 320×256, 640×512, 1280×1024, and 2048×2048, pixel pitches from 10μm to 30μm, and ADC quantization precision from 14-bit to 22-bit. Based on precise low-temperature simulation models built on domestic manufacturing processes, these ROICs support interconnect and integration with both cooled and uncooled infrared detectors. They feature key competitive advantages of high yield, low cost, and high performance.
