7.2.1
This pin is used as the analog output pin of the DAC8B1C module. The value represents the analog voltage
level between V
7.2.2
This pin serves as the power supply pin.l
7.2.3
This pin serves as an analog ground reference to the DAC.
7.2.4
This pin serves as the source for the high reference potential. Separation from the power supply pins
accommodates the filtering necessary to achieve the accuracy of which the system is capable.
7.2.5
This pin serves as the ground for the low reference potential. This pin is connected to V
DAC module boundary to accommodate the filtering necessary to achieve the accuracy of which the
system is capable.
