11 AC CHARACTERISTICS (ANALOG)
V
(pins 1, 11, 22 and 27); unless otherwise specified.
Notes
1. The input voltage can be up to 2 V (RMS) when the current through the ADC input pin is limited to approximately
2. The input voltage to the ADC scales proportionally with the power supply voltage.
3. The output voltage of the DAC scales proportionally with the power supply voltage.
