Using non-differential inputs:
When the non-differential inputs are used, the signal must enter at the non-negated input and
the negated input must be connected to the same GND as that of the module power supply.
In figure 5.4, there is an example where the module is powered with 5 V and the inputs are using
non-differential signals.

Note: When pin 12 is used to connect the power supply of 5 V, pin 13 must remain not connected.
