Analogue output from MP3 source

Hello

I have an MP3 module (JQ8400). Has DAC and Speaker output.

I have a small OLED display that shows a level indicator in the style of a bar graph. This takes it’s level from an analogue input pin.

Anyone got a simple circuit to take the audio output of the MP3 module and amplify it to a level I can use on the analogue in?

This is almost totally for show, but it would be nice to get it working.

Thanks
