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.

Light-to-Digital Converter

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. 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. While useful for general purpose light sensing applications, the TSL2580/81 devices are designed particularly for display panels (LCD, OLED, etc.) with the purpose of extending battery life and providing optimum viewing in diverse lighting conditions. Display panel backlighting, which can account for up to 30 to 40 percent of total platform power, can be automatically managed. Both devices are also ideal for controlling keyboard illumination based upon ambient lighting conditions. Illuminance info.
