![]() That means Vcm=14.5 volts, Vdiff=1.0 volts, and the expected Vout=1.0 To GND and Vneg is 14.0 volts compared to ground, and G=1. Figures for G=10 and G=100 are not available, but Vcm=10.0 volts and Vout=10.0 volts is not valid at G=1 or G=1000, so is certainly not valid for gains in between.Įxample #2: Say a differential signal is measured where Vpos is 15.0 volts compared That means Vcm=10.0 volts, Vdiff=0.1 volts, and the expected Vout=10.0 volts. Keep in mind that the voltage of any input compared to GND should be within the Vm+ and Vm- rails by at least 1.5 volts, so if Vm is the typical ☑3 volts, the signals should be within ☑1.5 volts compared to GND.Įxample #1: Say a differential signal is measured where Vpos is 10.05 volts compared to GND and Vneg is 9.95 volts compared to ground, and G=100. "Input Common-Mode Voltage" or Vcm is (Vpos + Vneg)/2. ![]() Following are figures showing the approximate signal range of the U6 analog inputs.
