OPT3101 ToF Sensors Texas Instruments OPT3101 Time-of-Flight (ToF) Sensors are high-speed, high-resolution analogue front end (AFE) for continuous-wave, ToF-based proximity sensing and range finding sensors. These sensors integrate the complete depth processing pipeline that includes the ADC, time sequencer, and the digital processing engine. The OPT3101 ToF sensors include a built-in illumination driver that covers most of the target applications. These sensors feature long-range distance measurement, de-aliasing to extend the distance range, obstacle detection and avoidance, and a sample rate of up to 4kHz. Typical applications include conveyor belt systems, factory automation, harsh environments, drones, vacuum cleaners, lawnmowers, robots, smoke detectors and emergency exits.
