Pin description
Table 1.
To obtain published performance, the analog V
respect to Analog Ground and Digital Ground, respectively. The decoupling is intended to
isolate digital noise from the analog section ; decoupling capacitors should be as close as
possible to the respective analog and digital supply pins.
All the ground pins must be tied together. In the following section, the ground and supply
pins are referred to as GND and V
Power Supply (5 pins)
Analog V
This pin is the positive analog power supply voltage for the DAC and the ADC section.
It is not internally connected to digital V
In any case the voltage on this pin must be higher or equal to the voltage of the Digital power
supply (DV
Digital VDD Supply (DVDD)
This pin is the positive digital power supply for DAC and ADC digital internal circuitry.
Analog Ground (AGND1, AGND2)
These pins are the ground return of the analog DAC (ADC) section.
