\[{{I}_{L}}=\frac{{{V}_{in}}}{R}\] Therefore, the load current is dependent upon the input voltage ‘V in ’ and the resistor ‘R’. Precautions had to be taken while the selection of measures load and feedback resistors R f and R L due to the below reasons. (i) When R f and R L are of very low values, the op-amp might be driven into saturation, since the …The input voltage of 1V (at first, without taking the feedback path into consideration) will appear at the non-inv. opamp node and will bring the output immediately into saturation (pos, supply voltage Vcc).In this case we can see that instead of being 0V, V – is actually 1.375 V due to the saturation of the op amp. The Effects of Saturation on the Inverting Op Amp. We have seen that the output, gain, and inverting input values of the inverting op amp change dramatically if the op amp saturates. These differences are noted in the table below:Real Op-Amp saturation doesn't look like that, nor does an idealised Op-Amp (which wouldn't saturate at all).
