ADR280 .1 - 10hz voltage noise

Question asked by JLP on May 29, 2013

I want to use a 1.2 volt precision reference for the midpoint in a single ended instrumentation amp.

On analog.com website parametric search, a voltage noise value of 2.2 uV p-p is listed for the ADR280.

Other parts such as the ADR441 list a voltage noise p-p value, but the ADR280 does not, nor is it apparent from the graphs.

The low frequency noise spec is important for my application.

I'm wondering if the noise spec listed in the parametric search is a reliable value, and if so how it is derived.

Thank you,

Jonathan
