The TSL2560 and TSL2561 are light-to-digital
converters that transform light intensity to a digital
signal output capable of direct I
SMBus (TSL2560) interface. Each device com-
bines one broadband photodiode (visible plus
infrared) and one infrared-responding photodiode
on a single CMOS integrated circuit capable of
providing a near-photopic response over an
effective 20-bit dynamic range (16-bit resolution).
Two integrating ADCs convert the photodiode
currents to 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 TSL2560 device
permits an SMB-Alert style interrupt, and the
TSL2561 device supports a traditional level style
interrupt that remains asserted until the firmware
clears it.
While useful for general purpose light sensing applications, the TSL2560/61 devices are designed particularly
for display panels (LCD, OLED, etc.) with the purpose of extending battery life and providing optimum viewing
in diverse lighting conditions. Display panel backlighting, which can account for up to 30 to 40 percent of total
platform power, can be automatically managed. Both devices are also ideal for controlling keyboard illumination
based upon ambient lighting conditions. Illuminance information can further be used to manage exposure
control in digital cameras. The TSL2560/61 devices are ideal in notebook/tablet PCs, LCD monitors, flat-panel
televisions, cell phones, and digital cameras. In addition, other applications include street light control, security
lighting, sunlight harvesting, machine vision, and automotive instrumentation clusters.
