What's the Vcm of AD173 if the VS is supplied by ±5V？

Jessie on Mar 5, 2021

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.

Hi,

Can you confirm if you have a typo error here?
Is it AD713 instead of AD173?

Thanks and regards!

Hi,

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!
