REFERENCE TERMINAL
The reference terminal may be used to offset the output by up
to ±10 V. This is useful when the load is “floating” or does not
share a ground with the rest of the system. It also provides a
direct means of injecting a precise offset. However, it must be
remembered that the total output swing is ±10 volts, from
ground, to be shared between signal and reference offset.
The AD625 reference terminal must be presented with nearly
zero impedance. Any significant resistance, including those
caused by PC layouts or other connection techniques, will increase the gain of the noninverting signal path, thereby, upsetting the common-mode rejection of the in-amp. Inadvertent
thermocouple connections created in the sense and reference
lines should also be avoided as they will directly affect th
