The transfer funciton with +-15V power supply is W=(x*Y)/10 +Z - Is the
transfer function unaffected when operating with +-8V power supply ? e.g X=3V,
Y=3V resulting in W=0.9V.  What happens if the device is operated with
unsymmetrical power supply (+15V, -8V). What is the impact to specified data
(Acurracy, Offset ...)?

 

Is the transfer function unaffected when operating with +-8V power supply ?
Ans: Yes, that is correct

What happens if the device is operated with unsymmetrical power supply (+15V,
-8V). What is the impact to specified data (Acurracy, Offset ...)?
Ans: The AD633 can run on asymmetrical supplies since there is enough headroom
with the +15V and -8V supplies. However, the AD633 unsymmetrical supplies have
not been characterized. Therefore, we cannot tell you the impact on accuracy.
Please be aware that if you use the devices outside the datasheet
specifications, we cannot guarantee its correct operation.
