Hi all,

Is there a way to connect an external power audio amplifier to Q2686’s SPK1N/SPK1P or SPK2N/SPK2P pins?

Are the schematics from WA\_ENG\_GEN\_APN\_002\_001 (Hands Free Speaker Phone) applicable?

I would like to avoid using the PCM output, if possible.

I would recommend you TPA731. Small and easy to use.
