OPT4001 Description
The OPT4001 is a light-to-digital sensor (single chip lux meter) that measures the intensity of visible light. The spectral response of the sensor tightly matches the photopic response of the human eye. A specially engineered filter on the device rejects nearinfrared ponent from the mon light sources to measure accurate light intensity.
OPT4001 Key Features
- 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 conditi
- 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
