Si115x Data Sheet Proximity/Ambient Light Sensor IC with I2C Interface The Si115x-AB00/AB09/AB9x is an ambient light sensor, proximity, and gesture detector with I2C digital interface and programmable-event interrupt output. This touchless sensor IC includes dual 23-bit analog-to-digital converters, an integrated high-sensitivity array of visible and infrared photodiodes, a digital signal processor, and up to three integrated LED drivers with programmable drive levels. The Si115x offers excellent performance under a wide dynamic range and a variety of light sources, including direct sunlight. The Si115x can also work under dark glass covers.
