The “three in one” SFH 7773 digital sensor from Osram Opto Semiconductors combines an infrared LED emitter with proximity and ambient light sensors in one compact unit. The sensor facilitates installation of proximity and ambient light sensing in smartphones and similar devices. It simplifies the elimination of crosstalk by combining the emitter and detector chips, circumventing the design requirements usually necessary to suppress crosstalk. Designers no longer have to install a separate IR emitter to enable the proximity sensor function. The SFH 7773 detects objects up to a distance of 15 cm, while simultaneously measuring the intensity of the ambient light. Its package measures 5.3 x 2.5 x 1.2 mm.
