First, I note that the VS can be supplied between ±4.5 and ±18.So I think the AD173 can be supplied by ±5V. I want to ask the the value of Vcm if the VS=±5V.
Thanks for the confirmation.
You are right that you can use +/- 5V supply for this part.
The Vcm requires +1.5V headroom from +Vs and -3.5V from -Vs.
Therefore, for supply range of +/- 5V, the Vcm will be +3.5V to -1.5V.
Thanks and regards!
