TSL2584TSV integrates one broadband photodiode (visible plus infrared), one infrared-responding photodiode, and a photopic infrared-blocking filter on a single CMOS integrated circuit. The integrated on-chip interference filter rejects IR producing a near-photopic response. TSL2584TSV's 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 is passed to a microprocessor where illuminance (ambient light level) in lux is derived using an empirical formula to approximate the human eye response. TSL2584TSV's near-photopic response produces a highly accurate lux measurement even when mounted behind dark glass.
The TSL2584TSV also supports an interrupt feature designed to simplify and improve system efficiency by eliminating the need to poll a sensor for a light intensity value.
