low power audio op amp?

Hi everyone, I was looking for a low power audio op amp for a project. I'll be using a 5V source and the input coming form pin 9 of an arduino to play wave audio file.

there is a lot of info about the lm386 but seems to be an old op amp. are there any better low power op amp than the lm386?

I'm trying to make it as loud as possible.
