Op Amp

Simple nonideal model of an op amp

 Description The Op Amp component is a simple nonideal model with output voltage limits implemented in a smooth manner. Note that the default gain ($\mathrm{Slope}$) is unity, which is unsuitable for most applications.
 Equations ${i}_{p}={i}_{n}=0$ ${i}_{\mathrm{max}}={i}_{\mathrm{min}}=0$ ${v}_{\mathrm{out}}=\frac{{v}_{\mathrm{max}}+{v}_{\mathrm{min}}}{2}+\frac{\left|\mathrm{Slope}\right|{v}_{\mathrm{in}}}{1+\left|\mathrm{Slope}\right|\left|\frac{2{v}_{\mathrm{in}}}{{v}_{\mathrm{max}}-{v}_{\mathrm{min}}}\right|}$ ${v}_{\mathrm{in}}={v}_{p}-{v}_{n}$
