Question
Are the adjustable resistor connections (e.g. A0, B0, W0) galvanically isolated
(separated) from the digital system ground (DGND/VSS) without any hard internal
connections on the chip?
Answer
These terminals, A0, B0, W0 are not isolated. All the AD5254's digital and
analog blocks share the same substrate.
