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
datasheet.

Note(s) and/or Footnote(s):
1. Optical measurements are made using small-angle incident radiation from light-emitting diode optical sources. Visible white LEDs
and infrared 850 nm LEDs are used for final product testing for compatibility with high-volume production.
2. The white LED irradiance is supplied by a white light-emitting diode with a nominal color temperature of 4000 K.
3. The 850 nm irradiance Ee is supplied by a GaAs light-emitting diode with the following typical characteristics: peak wavelength
λp = 850 nm and spectral halfwidth Δλ½ = 42 nm.
4. The integration time Tint, is dependent on the internal oscillator frequency (fOSC) and on the number of integration cycles (ITIME)
in the Timing Register as described in the register section. For nominal fOSC = 750 kHz, nominal Tint = 2.7 ms x ITIME.
5. 111x gain is affected by the line inductance between the VDD pin and the decoupling capacitor.
