AMS OSRAM GROUP TMF8828-1AM Distance Sensor, 5 m, I2C Digital, Time of Flight, 2.7 V to 3.3 V, PCB, TMF8828 Series

TMF8828-1AM is a multizone time-of-flight sensor. The dToF device is based on SPAD, TDC, and histogram technology and achieves a 5000 mm detection range. Due to its lens on the SPAD, it supports 3x3, 4x4, 3x6, and 8x8 multizone output data and a very wide, dynamically adjustable, field of view. A multi-lens array (MLA) inside the package above the VCSEL widens up the FoI (field of illumination). All processing of the raw data is performed on-chip and the TMF8828 provides distance information together with confidence values on its I²C interface. Application includes distance measurement for camera autofocus - Laser Detect Autofocus - LDAF (mobile phone), presence detection (computing and communication), object detection and collision avoidance (robotics), and light curtain (industrial).

• Enable new applications like click to focus, object tracking, presence detection
• Multizone with 3x3, 4x4, 3x6 and 8x8 zones
• Within ±3%/±10mm of measurement (accuracy), no multipath and no multiple object problems as for iToF
• Time-to-digital converter (TDC) direct time-of-flight measurement
• Single photon avalanche photodiode (SPAD) histogram based architecture
• No complex calibration, dynamic cover glass calibration
• Compensates for dirt on glass, reliable operation under demanding use cases
• Improved accuracy over temperature and life, reference SPAD
• Make better decisions, distance and signal quality reported
• OLGA12 package, operating ambient temperature range from -40 to 85°C
