ADS6102 series single-photon single-point ranging chips and dToF imaging
The ADS6102 is an integrated single-point dToF ranging chip jointly introduced with Shendun, reaching 5m with accuracy up to +/-1cm. It integrates a sensitive SPAD Array and laser driver, while the module includes an efficient infrared VCSEL. A single 3v supply requires no external clock or high-voltage source. More than 10 patentable dToF signal-processing algorithms and selectable frame rates, ranges, and accuracies provide simultaneous distance, brightness, and confidence for three targets, with I2C and high-speed SPI. Applications include camera focusing, proximity detection, smart homes, and industrial IoT.
