Si1120 sensors are high-sensitivity active infrared proximity and ambient light sensor ICs, enabling innovative touchless human interface applications with ultra-low power advantages.
The high-sensitivity infrared photodiode provides a single-pulse infrared proximity measurement, offering customers an opportunity to implement a proximity and ambient light sensor with ultra-low power levels. Consisting 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.
