Description

High-speed high-precision digital ambient light sensor (ALS) 8-SOT-5X3 -40 to 85

Features for the OPT4001:

• High precision, high speed light-to-digital conversion over high speed I2C interface in two package variants
• Precision optical filtering to closely match human eye with excellent near infrared (IR) rejection
• Semi-logarithmic output with 9 binary logarithmic full-scale light range and highly linear response within each range
• Built-in automatic full-scale light range selection logic, which switches measurement range based on input light condition with excellent gain matching between ranges
• 28 bits of effective dynamic range from
  • 312.5 µlux to 83 klux for PicoStar™ package variant
  • 437.5 µlux to 117 klux for SOT-5x3 package variant
• 12 configurable conversion times from 600 µs to 800 ms is an excellent choice for a wide variety of high speed and high precision applications
• External pin interrupt for hardware synchronized trigger and interrupts (only on SOT-5X3 package variant)
• Internal FIFO for output registers with I2C burst readout
