A file with a number of figures crashes on ViewPS or ViewDVI.
The attached file does the same with only a few math parts.
This started sometime this week, but that is a close a I know.

In general, the untuned CMRR can be calculated as:
\layout Standard
\begin_inset Formula $CMRR=20\log\left(\frac{100}{2\times Tol}\right)$
\end_inset
+20log
\begin_inset Formula $\left(A\right)$
\end_inset
, where Tol = the component tolerance and A = the differential gain.
\layout Standard
The critical components are R4, R5, R7, R8, R10, R11 and C5.
C5 controls the frequency response of the reference ampllifier, and is
caculated as:
\layout Standard
\begin_inset Formula $C5\cong\frac{0.16}{\left(R11*GBP\right)}$
\end_inset
, where GBP is the gain bandwidth product of the OPA251 (35,000).
