A Powerful New dToF Solution for Advanced Sensing Systems
Rutronik has expanded its sensing portfolio with the TMF8829 from ams OSRAM, a high-resolution Direct-Time-of-Flight (dToF) sensor engineered for applications requiring long range, fine depth accuracy and compact integration. The device combines a VCSEL light source, SPAD array and on-chip processing inside a miniature OLGA optical module, offering a measurement range up to 11 meters with an 80° diagonal field of view.
The sensor is suited for next-generation 3D applications including robotics, smartphone LDAF autofocus, depth mapping, SLAM and people-counting systems, where reliable, precise environmental awareness is essential.
High-Resolution Depth Modes and Robust Optical Architecture
The TMF8829 supports multiple resolution settings up to 48×32, enabling designers to tune depth output to application requirements. A multi-lens array and optimized SPAD optics expand the field of illumination, ensuring consistent performance across wider scenes.
The sensor maintains accuracy even with partially obstructed or contaminated optical covers, and its fine 0.25 mm distance resolution enables highly detailed depth information.
Its ability to detect multiple objects along a single line of sight supports complex, dynamic environments where traditional single-point ToF solutions fall short.

Flexible Interfaces for AI and Embedded Integration
Engineered for system versatility, the optical module includes I²C, I3C and SPI interfaces for high-speed data exchange. Raw histograms and processed algorithmic results can be streamed directly to host processors, making the sensor well suited for AI-assisted depth analysis and real-time fusion workloads.
With I/O supply options from 1.2 V to 3.0 V and reliable operation across –40 °C to +85 °C, the TMF8829 integrates easily into a wide range of embedded platforms.
Designed for Robotics, Mobile Devices and Smart Vision Systems
The sensor’s long range, high accuracy and compact footprint make it a strong candidate for autonomous robotic navigation, gesture recognition, indoor mapping and advanced smartphone camera functions such as laser autofocus and computational bokeh. By combining performance, robustness and integration flexibility, the TMF8829 helps engineers build next-generation sensing systems with greater reliability and spatial precision.
