The QuickSense Si1120 is the industry’s most sensitive active infrared proximity sensor IC enabling innovative touchless human interface applications with ultra-low power advantages. Comprised of an infrared LED driver, an infrared photodiode, an ambient light sensor and control logic, the device is packaged in a 3x3 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 microcontroller (MCU), the Si1120 proximity and ambient light sensor IC is capable of advanced motion and gesture recognition.
The Si1120 proximity and ambient light sensor IC is supported within the QuickSense Development Studio.
