Q
What is the input voltage range of AD8556 when supplied with 4V (4.096V)?
AD8556 will be used to amplify the output signal from a strain gauge bridge
supplied with the same voltage (4V). When AD8556 is supplied with 5V, the input
voltage range is 2.1-2.9V according to the datasheet. The common mode voltage
from the bridge will be 2V, when supplied with 4V.
A
We do not necessary characterized these non compliance spec information.
We did some check and test of interest.
Bench data on AD8556 shows that VCMi is ratiometric with VDD-VSS.

The table below is from the attached graphs of vosi & vout vs vcmi at 25C.
The measured values show proportionality to VDD.
