Dear team,

So do you have any latest recommendation solution for this application and replacement for NAU88U10. Thanks and looking forward to your reply.

They could look at TLV320AIC3100. It has a Mic input and a Class D Amp output that can drive 2.5w into 4 ohms.

Then it looks that the AIC3109-Q1+external ClassD Amplifier would be the only possibility
