The TSL2560 and TSL2561 are light-to-digital
converters that transform light intensity to a digital
signal output capable of direct I2C (TSL2561) or
SMBus (TSL2560) interface. Each device combines
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.
