2 POWER SUPPLY
2.3 Power Supply for Analog Circuits (AVDD)
The analog power supply pin (AVDD) is provided separately from the VDD and VDD pins in order that the digital circuits do not affect the analog circuit (A/D converter). The AVDD pin is used to supply an analog power voltage and the VSS pin is used as the analog ground.
Supply the same voltage level as the VDD to the AVDD pin.
AVDD = VDD, VSS = GND
Note: Be sure to supply VDD to the AVDD pin even if the analog circuit is not used.
Noise on the analog power lines decrease the A/D converting precision, so use a stabilized power supply and make the board pattern with consideration given to that.
