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