The TSL2560 and TSL2561 are light-to-digital converters that transform light intensity to a digital signal output
capable of direct I
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.
