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 13-53
shows the connection of eight
typical analog signal sources to one QADC64E analog input signal through a separate multiplexer chip.
Also, an example of an analog signal source connected directly to a QADC64E analog input channel is
displayed.
