0-10V analog from pwm

I need to get a 0-10V analog output from Nano 10 PWM output.
What would be the best solution ? I am thinking of using a voltage divider and capacitor.
Could you suggest a circuit? Any help or suggestions would be appreciated.
Thank you.

Texas Instrument has an excellent article on this topic:

You can also consider the FMD88-10 which has two channels of built-in DAC that can be configured for 0-5V or 0-10V output. FMD88-10 works identically as the Nano-10 except it has more digial and analog I/Os and a built-in LCD port.

Thank you for your help. We already use the FMD88 for other applications. we want to use the Nano 10 in this case.
We will try constructing a filter as suggested in the TI article.
