O DAC comment mode voltage. It should be connected to a 22 uF in parallel with a 0.1 uF
decoupling capacitors to ground. Signal level is AVDD/2.
GND DAC negative reference voltage. It should be tied to AGND.
I DAC positive reference voltage. It should be connected to AVDD via a 180 ohm serial
resistor, and a 22 uF in parallel with a 0.1 uF decoupling capacitors to ground.
No connection. It can be tied to AGND.
