General Description
TSL2580, TSL2581
Light-to-Digital Converter
The TSL2580 and TSL2581 are very-high sensitivity light-to-digital converters that transform light intensity to a digital signal output capable of direct I²C (TSL2581) or SMBus (TSL2580) 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 16-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.
