Profile: Silicon Laboratories Inc. specializes in providing mixed-signal integrated circuits (ICs). Our products include human interface, microcontrollers, isolation & power, audio & video, voice, wireless and modem products. The QuickSense™ Si1102 and Si1120 are sensitive active infrared proximity sensor ICs enabling innovative touchless human interface applications. They comprises of an infrared LED driver, an infrared photodiode, an ambient light sensor (Si1120) and control logic, the devices are 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.
