In summary, the Si1102/1120 provides very high performance and includes a high sensitivity infrared photodiode with a range of up to 50 cm and an innovative single pulse proximity sensor which is immune to fluorescent flicker and requires ultra low system power. The Si1120 has an integrated ambient light photodiode which reduces backlight power in low-light settings. Finally, Silicon Labs is addressing the needs of user interface development with its QuickSense Studio which includes patent pending touch-less slider and gestures as well as algorithms including background light type determination to help assist in the design process.
