Title: Introduction to Op-Amp Circuits Goal: To build and test basic operational amplifier circuits as an introduction to op-amp circuits. Virtual Equipment: Power supplies, DMMs, resistors, OP-AMP (741), breadboard, wires, TinkerCAD Preliminary: 1) 2) Determine resistor values for R. and Ri required to construct an inverting amplifier with your assigned gain. 1. Determine resistor values for R. and Ri required to construct a non-inverting amplifier with your assigned gain. Laboratory Procedure: (a) Select resistors with values as you specified in the preliminary. Calculate the expected gain of an inverting amplifier with these values. (b) Build an inverting amplifier using the resistors you've selected and set Vin for a DC value of 1V or 0.5V to avoid saturation. Adjust Vcc & Vee to the appropriate levels for your circuit (read the 741 datasheet for levels and pinout information). Display the voltage across the input terminal of the op-amp and the output of the circuit using DMMs. Measure the DC gain. How does the measured DC gain compare to your calculated gain from (a)? Repeat 1(a)-(b) for the non-inverting amplifier.
