OSRAM OPTO SFH 7773 ‘3 in 1′ digital sensor combines the functions of a digital ambient light sensor and a digital proximity sensor in a single compact unit. Device also simplifies the elimination of crosstalk by combining the emitter and detector chips together – eliminating the design requirements that are usually necessary to suppress crosstalk. Installation of a separate IR emitter to enable the proximity sensor function is no longer necessary. Device detects objects up to a distance of 15 cm (5.9 in.) while simultaneously measuring the intensity of the ambient light.
