TPA0253: Switching of SPK or Headphone

Part Number: TPA0253

Hi TI.

My customer need to simple audio amp.

And they found TPA0253.

They want to using speaker and headphone.

At normal situation, audio output is speaker.

When headphone is inserted to jack, audio output must be switched to only headphone.

Is TPA0253 available auto switching between speaker and headphone?

or

If headphone is inserted, audio output is speaker and headphone together?

Please let me know and if you have another solution, recommend.

Thanks

  • Hi SS,

    The application you're looking for is on data sheet page 2. There is a diagram that shows the connections to change from speaker to headphone when plug is inserted.
