3.3.2. Differential Analog Input 1 (TB202)
To interface to a single-ended (non-differential) voltage source, connect the signal common of the source to
the negative input and the analog source signal to the positive input. A floating signal source should be
referenced to the analog common as shown in
Figure 3-5 .
