switching between iir and fir filter on pcm5102

[PreSapian]

how do you toggle between the two filter modes on pcm5102 with physical means? i'd like to have a switch to select between the two. i understand pin 10 is the one to focus.

Pin 11 selects the interpolation Filter! Tie pin 11 to GND for FIR and to 3.3V (Dvdd) for low latency IIR Filter.

Thank you 🙂

So then pin 10 must be de emphasis. Do you toggle that the same way?

Yes: Pin 10 - Input - De-emphasis control for 44.1kHz sampling rate(1): Off (Low) / On (High)

Maybe you should take a look into the datasheet 😉

I did, and most of it is still garble to my untrained eyes 😛

So 3.3 to pin10 for 'on'?

Yes
