Overview
General Description TSL2561 Light-to-Digital Converter The TSL2561 are light-to-digital converters that transform light intensity to a digital signal output capable of direct I²C 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 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 TSL2561 devices are designed particularly for display panels (LCD, OLE...
