• The TSL2563 is low-voltage (2.5V) light-to-digital converter that transform light intensity to a digital signal
I2C interface. Device combines one broadband photodiode (visible plus infrared) and one infrared-
responding photodiode. Two integrating ADCs convert the photodiode currents to a I2C bus that represents
the irradiance measured on each channel.
• Display and keypad backlight intensity are controlled according to ALS output.
