  • Overview:

  • 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
