Hello guys,
I am trying to build a simple circuit using a stand alone educational op-amp (desktop type) with a DC power supply, couple resistors and a few lead wires. The op-amp is to maintain constant voltage across a potentiometer as the resistance of the this pot is varied using a T-type feedback network.
The op-amp model is this one https://www.thesciencesource.com/store/index.php?product_id=596&type=&category=
Our model lacks the inverting/non-inverting switch. If i make the proper connections to the positive and negative inputs of the op-amp, will it act in the inverting mode that i need it to?
The max gain is 100 and the circuit parameters i measure with this thing hooked up and running are not even remotely matching up to the ideal op-amp analysis. All the ground connections are connected to the negative sign connection on the power supply, and my circuit begins with a source, corresponding to the positive sign on the power supply.
Thank you for any suggestions. Is there a simple way i could verify that the op-amp is even working?
