TSL2584TSV Ambient Light Sensor

Light-to-Digital Converter with I²C interface


The TSL2584TSV is a very-high sensitivity light-to-digital converter that transforms light intensity into a digital signal output with a fast-mode I²C interface. The device combines one broadband photodiode (visible plus infrared), one infrared-responding photodiode, and a photopic infrared-blocking filter on a single CMOS integrated circuit. Two integrating analog to Digital Converters (ADCs) convert the photodiode currents into a digital output that represents the irradiance measured on each channel. This digital output can be input to a microprocessor where illuminance (ambient light level) in lux is derived using an empirical formula to approximate the human eye response. The TSL2584TSV supports a traditional level style interrupt that remains asserted until the firmware clears it.
