QWe are using one of your competitor Instrumentation Amplifier for a shunt based
valve control, which is now displaying increased offset voltage at very low
Vsense voltages (below 1V VCM). Your competition describes that issue in the
datasheet. Does your products have similar issues as we did not find a remark
in the datasheet?
AOur parts do not have this behavior. Our parts will have lower swing
limitation, so that in a unidirectional configuration, as the output tries to
go to 0V, the output will be limited by swing, but this limit is static,
unrelated to common mode, and of much lower magnitude than the competitor part.
I would start with recommending the AD8208 as the latest generation in that
The AD8418A is also an option as a high performance, lower cost option, but
does not have 8kV ESD protection like the AD8208 has.
