Notes
1.
The input voltage can be up to 2 V (RMS) when the current through the ADC input pin is limited to approximately
1 mA by using a series resistor.
The input voltage to the ADC scales proportionally with the power supply voltage.
The output voltage of the DAC scales proportionally with the power supply voltage.
