I'm using the AD8274 to measure the voltage of a cell (2V to 5V), with a 0V +7V supply voltage, coming form a buck converter. I'm using the G=1/2 configuration.
It looks the maximum common-mode voltage I can apply is +16V, then the output voltage saturates to 7V. The minimum I can apply is 0.7V, but this is not a problem for me, since I will have only positive common-mode voltage. Is this normal for you ? I was expecting it to stand a higher common-mode voltage.
Can I connect the output to the adc directely or do you suggest to have a voltage follower before ?
Thank you for your help.
