Lab #5 Overview Activity #1 - Simulation of an Op-Amp inverting amplifier Activity #2 - Build and Test the Op-Amp inverting amplifier Activity #3 - Determining the Gain and Saturation of the Op-Amp inverting amplifier

Simulation Run the simulated circuit found in the class folder (Lab_5_Circuit.msm) Notice that a negative voltage is used as the input to produce a positive output voltage The gain is the output divided by the input

Build and Test Build and test the circuit Measure each resistor before assembling into the circuit, so you can find the current through each resistor later

Photo #1 - Power Connections on the Proto-Board Make sure there is visible wire at the terminals, so that the terminals are not clamping down on the wire insulation

Vout R1 R5 R4 R3 R C2 C1 R7 R6 At this end there will be a cut-out and/or a dot next to pin 1 -15V ground +15V ground Vin Photo #2 An example circuit layout of figure 5 on page 4 of the lab

Vin Photo #3 - Vin Connections from the HP DC Power Supply

Determining Saturation Change the input voltage until the output stops going up ( it has reached saturation) Switching the leads on the DC power supply enable you to get positive voltages on the inputs (and negative output voltages)
