AUXILIARY ADC PINS

The ADAU1466 has a 10 bit, successive approximation
register (SAR) ADC multiplexed across six input channels.
Channel AUXADC0 and Channel AUXADC1 are connected
to linear Potentiometer R1 and Potentiometer R2.
Channel AUXADC2 to Channel AUXADC5 are accessible
on test points next to the ADAU1466. Inputs to the ADCs
between 0 V and 3.3 V can be connected to these pads and then
used in the SigmaStudio signal flow (see Figure 66).
