The SGM2549D senses ground pole and automatically selects switches accordingly in either the driver side or the headset side, with no need of any external control input. If a plug-in of the earphone is misplaced, it will keep SGM2549D trying periodically until a correct microphone pole is found. It consumes 1.3μA when a microphone is identified.
SGM2549D is available in Green UTDFN-1.5×2-6L and SOT-23-6 packages. It is rated over the -40℃ to +85℃ temperature range.
