With a built-in 16-bit ADC and I2C interface, it enables spectral analysis in a tiny OSLP package. The dedicated flicker detection engine can detect light source flicker up to 1kHz, critical for camera exposure control and display quality assessment.","working_principle":"The AS7341 uses an array of photodiodes with on-chip interference filters that pass specific narrow wavelength bands. Each of the 8 visible channels measures light intensity in a specific spectral band (F1-F8 covering approximately 415nm-680nm). The NIR channel extends detection to near-infrared wavelengths. The clear channel measures total visible light without filtering. The flicker detection channel uses a separate photodiode with dedicated circuitry to detect periodic light variations. The integrated 16-bit ADC converts photocurrents to digital values with programmable gain and integration time. Results are read via I2C.","pin_description":"
