ams OSRAM TMF8801 1D Time-of-Flight Distance Sensors

ams OSRAM TMF8801 1D Time-of-Flight Distance Sensors offer highly accurate depth accuracy detection through a sub-nanosecond light pulse and an anti-aliasing "stop-watch" method to measure the round-trip time of the pulse. The TMF8801 provides single-zone detection of an object irrespective of color, reflectivity, and texture. These modules with a VCSEL emitter offer a high dynamic range and detection sensing measurements with a 20mm to 2500mm distance range. TMF8801 utilizes highly sensitive Single-Photon Avalanche Diode (SPAD) detection with fast, compact time-to-digital converters to make highly accurate distance measurements within ±5%. It can operate in dark environments and in the presence of sunlight.

The on-chip histogram processing of the TMF8801 enables the device to detect cover glass and compensate for dirt, smudges, or contaminants, ensuring a high Signal-to-Noise Ratio (SNR). The histogram delivers dynamic cover glass calibration and crosstalk compensation, while background light noise is minimized through on-chip sunlight rejection filters. Data output is handled through a 1.8V, I2C fast-mode communications interface.
