SI1153-AA9X-GM

Si1153 Data Sheet Proximity/Ambient Light Sensor IC with I2C Interface KEY FEATURES The Si1153-AA00/AA09/AA9x 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 three integrated LED drivers with programmable drive levels. The Si1153 offers excellent performance under a wide dynamic range and a variety of light sources, including direct sunlight. The Si1153 can 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, the Si1153 is capable of supporting multiple-axis proximity motion detection. The Si1153 is provided in a 10-lead 2x2 mm DFN package or in a 10-lead 2.9x4.9 mm LGA module with integrated LED, and is capable of operation from 1.62 to 3.6 V over the –40 to +85 °C temperature range.
