The QuickSense Si1120 is the industry’s most sensitive active infrared proximity and ambient light sensor IC, enabling innovative touchless human interface applications with ultra-low power advantages. Consisting of an infrared LED driver, an infrared photodiode, an ambient light sensor and control logic, the device is packaged in a 3 mm x 3 mm clear DFN. The high-sensitivity infrared photodiode provides a single-pulse infrared proximity measurement, offering customers an opportunity to implement infrared light emitting diodes with unusually low power levels. When combined with a Silicon Labs capacitive touch-sense MCU, the Si1120 is capable of advanced motion and gesture recognition. The Si1120 proximity and ambient light sensor IC is supported within the
QuickSense Development Studio.
