AD8218 If "ENB" is tied to ground

Q

If “ENB” is tied to ground, does the input need to larger than 5mV if we want
to gurantee the spec on page 3 in the datasheet? In figure 32, seems the input
can be 0mV, but in figure 7, the total output error is larger if the input is
less than 5mV. Do you have any comments about this?

A

No, with the enable pin on, meaning output starts at 80mV, we guarantee the
same gain, offset, and CMRR but there is an additional error that is specified
in here.
