How the Op Amp Diagram 741 Works
The 741 op amp operates based on the principle of negative feedback. The input signal is applied to the inverting and non-inverting inputs, and the output is taken from the output terminal. The internal circuitry of the 741 op amp consists of a differential input stage, a voltage amplifier stage, and an output stage.
The differential input stage compares the voltage at the inverting and non-inverting inputs. The voltage amplifier stage amplifies the difference between the two inputs. The output stage drives the output terminal, which is connected to the load through a feedback network. The feedback network ensures that the output voltage is proportional to the input voltage, thus maintaining a stable gain.
