Next, connect the non- inverting input (pin 3) directly te ground rail of thee breadboard. This estables the virtual ground reference. The inverting input (pin 2) will servie as the summing junction where the input resistor and beedback resistor connect.

Install thee input resistor Ri between thee signal input terminal and the inverting input (pin 2). Use a resistor value appropriate for your desired input impedance and gain range. A 10 křesistor is a standard starting point.

Install thee variable resistor or potentiometer as the feed back element. If using a standard potentiometer, connect one end terminal the exput (pin 6) and the wiper terminal to the inverting input (pin 2).

This condition is specilarly requiant whene thee feed back network inputes additional faxe shift, such as when driving capacitiva loads or using long feedback wires.

Tu ensure stable operation, follow these guidelines:

  • Keep feeback path wiring as short as possible to co minimize parasitic inductance andd capacitance.
  • Usie sockets for thee op- amp to allow easy replacement if needed.
  • Dodać a small resistor (typically 50 mbH to 100 mbH) in serie with thee output to isolate capacitiva loads.

Most general- intence op- amps like thee LM741 and TL081 are internally compensated and stable for closed-loop gains of unity or higher. However, thee additional faxe shift introduced ed by thee potentiometer in thee feed back path can sometimes cause stability issues at extreme gain settings.
