Title: 0-10V analog from pwm
Post by: mijoe on November 14, 2011, 01:30:45 PM

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.
