Features

  • Direct ToF technology with high sensitivity SPAD detection
  • Fast Time-to-Digital Converter (TDC) architecture
  • Sub-nanosecond light pulse
  • 0 – 10cm proximity detection and 10 – 60cm distance sensing @ 60Hz
  • On-chip histogram processing
  • 940nm VCSEL Class 1 Eye Safety with 21° FOI
  • Sunlight on-chip rejection filter and algorithm
  • Industry’s smallest modular OLGA 2.2mm x 3.6mm x 1.0 mm package

Benefits

  • Delivers high SNR, wide dynamic range and no multi-path reflections
  • Enables “dark and sunlight environment” distance measurement within ±5%
  • Provides best-in-class resolution ranging mode detection sensing
  • Enables cm detect/release proximity events
  • Provides high accuracy, greater distance between cover glass, dynamic cover glass calibration, dirt or smudge removal and crosstalk compensation
  • Eye-safety circuitry stops VCSEL driver if VCSEL fault occurs
  • Optical filters with algorithm support enables high ambient light resilience
  • Reduce board space requirements, enables low-profile system designs in restricted space Industrial Designs
