ADAU1772 output analog filter

Hi,

I would like to know if it is a good idea to add an external Low Pass filter to the ADAU1772 at analog output? I understand that a High-pass filter is necessary to remove the DC from the output, but what about a low pass filter? I don't think it is necessary, but I would like to know your opinion about that.

Best Regards,

Denis
