Summary
\begin{align}
v_{nt}(1\;\mathrm{kHz},300\;\mathrm{K}) &= \sqrt{ \quad 4kTR_i \quad + 4kT \left(R_{f_1}^{-1} + R_{f_2}^{-1}\right)^{-1} + \qquad e_n^2 \qquad + \quad\; e_{n,ref}^2 \quad\;+ i_n^2 \left[ R_i^2 + \left(R_{f_1}^{-1} + R_{f_2}^{-1}\right)^{-2}\right]}\\
&\approx \sqrt{\left(10.2\;\frac{\mathrm{nV}}{\sqrt{\mathrm{Hz}}}\right)^2 + \left(10.0\frac{\mathrm{nV}}{\sqrt{\mathrm{Hz}}}\right)^2 + \left(0.9\frac{\mathrm{nV}}{\sqrt{\mathrm{Hz}}}\right)^2 + \left(50\frac{\mathrm{nV}}{\sqrt{\mathrm{Hz}}}\right)^2 + \qquad \left(17.4\frac{\mathrm{nV}}{\sqrt{\mathrm{Hz}}}\right)^2}\\
&\approx 55 \frac{\mathrm{nV}}{\sqrt{\mathrm{Hz}}}
\end{align}
