Each device com- ADDR SEL 2 5 INT bines one broadband photodiode (visible plus infrared) and one infrared-responding photodiode GND 3 4 SCL on a single CMOS integrated circuit capable of providing a near-photopic response over an effective 20-bit dynamic range (16-bit resolution). PACKAGE CL Two integrating ADCs convert the photodiode 6-LEAD ChipLED currents to a digital output that represents the (TOP VIEW) irradiance measured on each channel. This digital SDA 5 4 SCL output can be input to a microprocessor where illuminance (ambient light level) in lux is derived INT 6 3 ADDR SEL using an empirical formula to approximate the human eye response. The TSL2560 device V 1 2 GND permits an SMB-Alert style interrupt, and the DD TSL2561 device supports a traditional level style Package Drawings are Not to Scale interrupt that remains asserted until the firmware clears it. While useful for general purpose light sensing applications, the TSL2560/61 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 information can further be used to manage exposure control in digital cameras. The TSL2560/61 devices are ideal in notebook/tablet PCs, LCD monitors, flat-panel televisions, cell phones, and digital cameras. In addition, other applications include street light control, security lighting, sunlight harvesting, machine vision, and automotive instrumentation clusters.
