SBOS993A December 2021 – December 2022 OPT4001
PRODUCTION DATA
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 near-infrared component from the common light sources to measure accurate light intensity. Output of OPT4001 is semi-logarithmic with 9 binary logarithmic full-scale light ranges along with highly linear response within each range, bringing capability to measure from 312.5 μlux to 83 klux for PicoStar™ variant and 437.5 μlux to 117 klux for the SOT-5X3 variant. This capability allows light sensor to have 28-bit effective dynamic range. With built-in automatic full-scale range selection, logic users do not have to select appropriate gain settings based on light levels.
