Hi,

According to datasheet of PCM5100, we can see the typical analog output value is 2.1Vrms but maximum value is not.

Do you know the max analog output value?

Hi,

I measured PCM5102 which is almost same like PCM5100 with my oscilloscope and the Peak-Peak voltage is almost 6 volts with maximum 0dB digital signal.

You can look on my page with more measured DACs: http://www.pavouk.org/hw/dacshapes/en_index.html

This specification is given by the gain error in the datasheet.
We specify typical at 2.1VRMS, but this can vary by +/- 6%
