Other Parts Discussed in Thread: OPT3101

Hi team,

Could you please kindly help recommend a TOF sensor?

Requirements:

Vin: 3V~3.5V,

VI4302,

resolution:1mm,

SPAD photon detection efficiency: 6%@905nm

LGA28_50-VI4302

Thanks,

Brian

    Hi Brian,

    The only ToF device we have is the OPT3101, typically used for Long-Range Distance measurements, Obstacle Detection and Avoidance.

    Brian,

      The OPT3101 device is a high-speed, high-resolution AFE for continuous-wave, time-of-flight based proximity sensing and range finding. The device integrates the complete depth processing pipeline that includes the ADC, timing sequencer, and the digital processing engine. The device also has a built in illumination driver that covers most of the target applications. Given the high ambient rejection ratio, the device can support very high ambient conditions, including full sunlight of 130k lux. The timing sequencer is highly configurable to provide for application-specific trade-offs of power versus performance. The device provides depth data that consists of phase, amplitude, and ambient measurements.

    The OPT3101 is not based on SPAD photon detection. Our packaging is VQFN (28) 5.00 mm × 4.00 mm. 

    The OPT3101 AFE connects to an external illuminator (LED, VCSEL, or LASER) to transmit modulated optical signals, and reflected signals are received by an external photodiode which connects to the input of the AFE. The received signal is converted to amplitude and phase information by the AFE and depth engine. 

    Our detection method is superior to SPAD and is immune to ambient light.
