Hello,
We are using the PCM6020-Q1 and I was wondering what is the voltage of Vref, in the datasheet it said:
"All audio data converters require a DC reference voltage. The PCM6020-Q1 achieves its low-noise performance
by internally generating a low-noise reference voltage. This reference voltage is generated using a band-gap
circuit with good PSRR performance. This audio converter reference voltage must be filtered externally using a
minimum 1-μF capacitor connected from the VREF pin to the analog ground (AVSS)."
But I couldn't find the value of this voltage in the DS , can you help on this topic ? it would prevent from DC biais trouble and BOM harmonization.
