QuickSense™ Si1102 and Si1120 Infrared Sensor ICs

The QuickSense Si1102 and Si1120 are the industry’s most sensitive active infrared proximity sensor ICs enabling innovative touchless human interface applications with ultra-low power advantages. Comprised 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.
