The TSL2562 and TSL2563 are low-voltage light-to-digital converters that transform light intensity to a digital
signal output capable of direct I
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
TSL2562 device permits an SMB-Alert style interrupt, and the TSL2563 device supports a traditional level style
interrupt that remains asserted until the firmware clears it.
While useful for general purpose light sensing applications, the TSL2562/63 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 TSL2562/63 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.

... ADDR SEL Detailed Description The TSL2562 and TSL2563 are second-generation ambient light sensor devices. Each contains two integrating analog-to-digital converters (ADC) that integrate currents from two photodiodes. Integration of both channels occurs simultaneously. Upon completion of the conversion cycle, the conversion result is transferred to the Channel 0 and Channel 1 data registers, respectively ...
