Analog Inputs  
Common  
The analog inputs must be free of noise with respect to AGND.  
The common pin defines the zero reference point for all single ended inputs. It must be free  
of noise and is usually tied to the analog ground plane.

DGND  
AGND  
DigitalGround  
This is the ground for the internal logic. Tie to the ground plane.  
AGND should be tied directly to the analog ground plane.  
Tie V to most negative potential in the circuit. (Ground in single supply applications.)  
The reference inputs must be kept free of noise with respect to AGND.  
A logic low on this input enables data transfer.  
The A/D conversion result is shifted out of this output.  
The A/D configuration word is shifted into this input.  
This clock synchronizes the serial data transfer.  
This clock controls the A/D conversion process.  
This supply must be kept free of noise and ripple by bypassing directly to the analog ground  
plane.
