The device features precision optical filtering and high infrared rejection (>99% at \u00b185\u00b0 incidence), enabling accurate measurement under various light sources including those behind dark glass. The automatic full-scale setting feature simplifies software design by eliminating manual range selection, allowing measurement across the full 0.01 lux to 83,000 lux range with 23-bit effective dynamic range. The 2 mm \u00d7 2 mm USON package minimizes board space in portable applications.","working_principle":"The OPT3004 uses a photodiode with an integrated optical filter that precisely matches the photopic response of the human eye while blocking infrared wavelengths. The filtered photodiode current is converted to a digital value by a sigma-delta ADC. The automatic full-scale setting mechanism monitors the output and dynamically selects the optimal gain range from 12 binary-weighted settings, with less than 0.2% matching between ranges. This ensures maximum resolution across the full 0.01-83,000 lux range without user intervention. The I2C\/SMBus interface provides access to measurement results and configuration registers. An interrupt pin can be configured for threshold-based alerts. The device operates from 1.6 V to 3.6 V with 5.5 V tolerant I\/O, consuming only 1.8 \u00b5A in active measurement mode.","pin_description":"\n
