TSL2584TSV
TSL2584TSV
Light-to-Digital Device
General Description
The TSL2584TSV is a very-high sensitivity light-to-digital
converter that transforms light intensity into a digital signal
output capable of direct 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 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.
Ordering Information and Content Guide appear at end of
