Information
Inverting Op Amp
An operational amplifier (often op-amp) is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended out put.
Below is a link to the Texas Instruments 741 Operational Amplifier Spec Sheet that goes in depth on configuration and functions of the circuit:
