The SIF1010 is a direct time-of-flight (dToF) optical distance sensor. Utilizing advanced SPAD technology, this sensor boasts high quantum efficiency, enabling ultra-low power consumption. For most measurement distances, target distance accuracy is ±5%. The device incorporates crosstalk suppression, dirt 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 frame rates up to 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 SIF1010 include cliff detection, stair detection, and collision avoidance.
