... 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 TSL2580 device permits an SMB-Alert style interrupt, and the TSL2581 device supports a traditional level style interrupt that remains asserted until the firmware clears it. ...

... ADDR SEL Detailed Description The TSL2580 and TSL2581 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 ...
