Evaluating with the ADCPro Software

9.1.1 MUX Tab

The ADS1258 multiplexer can work in two modes, selected by the controls Fixed Channel or Auto Scan.

When set to Fixed Channel mode, the screen will appear as shown in Figure 21.

Figure 21. Mux Settings for Fixed Channel Mode

On the Fixed Channel tab, the AINP and AINN of the ADS1258 are connected to the pins selected by the

radio buttons. In Figure 18, these are both set to AIN0—not a useful setting for measuring an input signal,

but quite commonly used for noise testing of the ADS1258. Any channel may be referenced to any other

channel; for example, if AINP were set to AIN1, and AINN were set to AIN0, then the signal could be

applied between AIN1 and AIN0.
