Default PWM to Analog conversion.

Hi,

I'm building an amplifier with the TAS5518 processor.
I wish to use also the PWM output from it for the headphones.
Can somebody tell me how to convert the TAS5518 Differential PWM Output to analog to be used with a standard OpAmp?
Thank You very much.

Resistor and capacitor is simplest into non inverting input of op-amp.

IR2113 is another option.

Well... yes, a low pass filter can convert "PWM to analog", but for high quality DVDD and DVSS must be perfectly clean, wich is not automatically true!
