5.2 Analog Output Filter Configuration
The following table lists the components that must be present or absent in order to realize each filter design
for each of the four output channels. “POPULATE” or a component value specifies that the component
should be populated, while “NO POP” specifies that the component should not be populated.
Notes:
2. Nonzero resistors are specified as 1/10 W with 1% tolerance.
