I also agree on Jim's and your preference for the 3280.
But just as an additional hint, the 3280 *also* has its input voltage
divided down into the 100mV range. The diodes are the "shunt"
part of the voltage divider.

I killed one, because I was so sure the data sheet maximum rating was
a typo. 8-(   Do you know what is the "weak link" here? The silicon?
The bond wires?
