SGM5101 & SGM5100 Single-Ended Input Configuration: AIN+ & AIN- Connections

To operate the single-ended input of SGM5101, the input signal should be connected to AIN^+ and AIN^- should be linked to either 1.5 V or V_CM. Conversely, for the single-ended input of SGM5100, the input signal should be connected to AIN^+ and AIN^- should be connected to V_CM or a low noise reference voltage ranging from 0.5 V to 1.5 V.'}
