概要
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.

TSL2540
The TSL2540 is a very-high sensitivity light-to-digital converter that approximates the human eye response to light intensity under varying lighting conditions and transforms this light intensity to a digital signal output capable through a 1.8V I²C interface. The ALS sensor features 2 output channels, a visible channel and an IR channel. The visible channel has a photodiode with a photopic Interferometric UV and IR blocking filter and the IR channel has a photodiode with an IR pass filter. Each channel has a dedicated integrating data converter which converts photodiode current into a 16-bit digital output. This digital output can be interfaced with a microprocessor where illuminance in lux is derived to accurately measure ambient light to control a displays backlight.
