Signal Connection Considerations
27.9.6 Analog Input Considerations
The source impedance of the analog signal to be measured and any intermediate filtering
should be considered whether external multiplexing is used or not. Figure 27-52 shows the
connection of eight typical analog signal sources to one QADC analog input signal through
a separate multiplexer chip. Also, an example of an analog signal source connected directly
to a QADC analog input channel is displayed.
