open-in-new Find other Time of flight (ToF) sensors


The OPT8241 time-of-flight (ToF) sensor is part of the TI 3D ToF image sensor family. The device combines ToF sensing with an optimally-designed analog-to-digital converter (ADC) and a versatile, programmable timing generator (TG). The device offers quarter video graphics array (QVGA 320 x 240) resolution data at frame rates up to 150 frames per second (600 readouts per second).

The built-in TG controls the reset, modulation, readout, and digitization sequence. The programmability of the TG offers flexibility to optimize for various depth-sensing performance metrics (such as power, motion robustness, signal-to-noise ratio, and ambient cancellation).
