This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.

AMS TMF8801 1D Time-of-Flight Sensor

AMS TMF8801 1D Time-of-Flight Sensors provide fast and accurate distance detection in virtually any environment. 

The TMF8801 performs direct time-of-flight measurements using a 940nm VCSEL emitter, highly sensitive Single-Photon Avalance Diode detection, and a fast Time-to-Digital converter architecture. The sensor can operate in dark or sunlit environments while providing distance measurements from 20mm to 2500mm with ±5% accuracy, irrespective of the color, reflectivity, or texture of the object. 

The TMF8801 also has on-chip histogram processing that provides a high SNR while providing dynamic cover glass calibration and compensating for contaminants. The AMS TMF8801 1D time-of-flight sensor is housed in a compact 2.2mm x 3.6mm x 1.0mm package for use in tiny spaces such as display bezels and operates from a 2.7V to 3.3V supply.
