@ -152,10 +152,13 @@ conditions under which the op-amp amplifies higher and lower
frequencies than would be specified under generic ``open-loop gain'':
for example, the LM741 datasheet documents the \textit{Open-Loop
Large-Signal Differential Voltage Amplification} as a function of
frequency, as seen in Figure \ref{img:lm741_oclsg}. This differs from
``open-loop gain'' in that the operating output is known to be a
meaningful fraction of the supply voltage; here, it is
$V_o = \SI{10}{V}$ for $V_{CC} = \pm \SI{15}{V}$.
frequency, as seen in Figure \ref{img:lm741_oclsg}. Despite being
closely related to ``open-loop gain'', it is distinct in that it is
measured with an output load (in this case, $R_L = \SI{2}{\kohm}$),
and under conditions such that the load is significant, i.e. that the
operating output is known to be a meaningful fraction of the supply
voltage \cite{b1}. Here, it is $V_o = \SI{10}{V}$ for
$V_{CC} = \pm \SI{15}{V}$.
