The SIF1080 is a direct time-of-flight (dToF) optical distance sensor with a target detection range exceeding 5 meters. Utilizing advanced SPAD technology, this sensor boasts high quantum efficiency, enabling ultra-low power consumption. For most measurement distances, target relative distance accuracy is ±5%. The device incorporates crosstalk suppression, occlusion compensation, stacking calibration, software pixel binning, ambient light suppression, and flexible frame control and configuration. It supports full histogram or direct depth output modes with a maximum frame rate of 120fps. A wide voltage range I2C interface (1.2V/1.8V/3.3V) is compatible for receiving control and transmitting data. Target applications for the SIF1080 include camera autofocus, presence detection, and collision avoidance.
