onsemi NCS2302
The NCS2302 is a compact and cost effective headset detection interface IC. It integrates several circuit blocks to detect the presence of a stereo headset with a microphone and whether the send/end button has been pressed. The NMOS transistor on the MIC pin mutes the signal when the headset is not present.| Part No. | NCS2302 |
