Recommended Output Filter for the PCM510xA
The diagram in Figure 43 shows the recommended output filter for the PCM510xA. The new PCM510xA next
generation current segment architecture offers excellent out of band noise, making a traditional 20kHz low pass
filter a thing of the past.
The RC settings below offer a â3dB filter point at 153kHz (approx), giving the DAC the ability to reproduce
virtually all frequencies through to itâs maximum sampling rate of 384kHz.
