Si115x Proximity and Ambient Light Sensor IC with I2C Interface

Our Si115x solutions are ambient light sensors, proximity and gesture detectors with an I²C digital interface and programmable-event interrupt output. Si115x sensor ICs include 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.

Si115x offers excellent performance under a wide dynamic range and a variety of light sources, including direct sunlight. Si115x sensors also work under dark glass covers. The photodiode response and associated digital conversion circuitry provide excellent immunity to artificial light flicker noise and natural light flutter noise. With two or more LEDs, Si115x sensors are capable of supporting multiple-axis proximity motion detection.
