Notes
1. Strongly depends on the external decoupling capacitor connected to Vref(DA).
2. Cref in F.
3. Although a level of 1.414 V (RMS) would be required to optimal drive the ADC in this gain setting, this level can not
be used. Due to the 3.3 V supply voltage input, signals of 1.17 V (RMS) and higher will result in clipping.
4. Measured with the APLL as ADC clock source.
5. Measured with I2S-bus input as digital source.
