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 is inversely proportional with the supply voltage.
The output voltage of the UDA1344TS differs from the output voltage of the UDA1340M.
The output of the DAC scales proportionally with the supply voltage.
