MCP3204/3208
6.5
The MCP3204/3208 devices provide both digital and
analog ground connections to provide another means
of noise reduction. As shown in
and digital circuitry is separated internal to the device.
This reduces noise from the digital portion of the device
being coupled into the analog portion of the device. The
two grounds are connected internally through the
substrate, which has a resistance of 5 -10Ω.
If no ground plane is utilized, then both grounds must
be connected to V
available, both digital and analog ground pins should
be connected to the analog ground plane. If both an
analog and a digital ground plane are available, both
the digital and the analog ground pins should be
connected to the analog ground plane. Following these
steps will reduce the amount of digital noise from the
rest of the board being coupled into the A/D converter.
