AD627  
If there is only one power supply available, it must be shared by  
both digital and analog circuitry. Figure 41 shows how to minimize  
interference between the digital and analog circuitry. As in the  
previous case, use separate analog and digital ground planes or  
use reasonably thick traces as an alternative to a digital ground  
plane. Connect the ground planes at the ground pin of the power  
supply. Run separate traces (or power planesꢀ from the power  
supply to the supply pins of the digital and analog circuits. Ideally,  
each device should have its own power supply trace, but they  
can be shared by multiple devices if a single trace is not used to  
route current to both digital and analog circuitry.  
LAYOUT AND GROUNDING  
The use of ground planes is recommended to minimize the  
impedance of ground returns (and hence, the size of dc errorsꢀ.  
To isolate low level analog signals from a noisy digital environment,  
many data acquisition components have separate analog and  
digital ground returns (see Figure 47ꢀ. Return all ground pins  
from mixed-signal components, such as analog-to-digital  
converters, through the high quality analog ground plane.  
Digital ground lines of mixed-signal components should also  
be returned through the analog ground plane. This may seem  
to break the rule of separating analog and digital grounds;  
however, in general, there is also a requirement to keep the  
voltage difference between digital and analog grounds on a  
converter as small as possible (typically, <0.3 Vꢀ. The increased  
noise, caused by the digital return currents of the converter  
flowing through the analog ground plane, is generally negligible.  
To maximize isolation between analog and digital, connect the  
ground planes back at the supplies.
