Light-to-Digital
Light-to-Digital (LTD) sensors combine a broadband photodiode (350nm to 1100nm) with a visible light blocking photodiode in a single CMOS integrated circuit. With integrated analog-to-digital conversion circuitry, data is output via a serial interface using two standard protocols: SMBus and I2C. Light intensity in Lux (i.e. luminance) can be easily calculated using the output from both photodiodes without the need of using an expensive optical filter. LTD sensors are commonly used in ambient light sensing applications for display management in cell phones, TVs, notebooks, tablets, and other display-based products. Other applications include street light control, security lighting, sunlight harvesting, machine vision, and automotive instrumentation clusters.
