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 28-52
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.
