4.2 Component Demonstration
Follow these steps to demonstrate the correct operation of an op-amp and the VirtualBench DC power supply, function
generator (FGEN), and mixed-signal oscilloscope (MSO).
Parts List
● One UA741CN op-amp
● One breadboard
● Jumper wires
Build the interface circuit: Refer to the schematic diagram (Figure 4.4) and recommended breadboard layout (Figure
4.5) as well as the VirtualBench setup (Figure 4.6).
Figure 4.4. Demonstration Circuit for Op-Amp
The interface circuit requires the following connections to the VirtualBench device.
 Op-amp positive power supply -> DC power supply +25 V pin
 Op-amp negative power supply -> DC power supply ground pin
 Op-amp noninverting input (V_in) -> FGEN positive lead
 Op-amp inverting input (V_ref) -> DC power supply +6 V pin
 Op-amp inverting input (V_ref) -> MSO CH 1
 Op amp output (V_out) -> MSO CH 2
 MSO CH 1 ground -> DC power supply signal ground
 MSO CH 2 ground -> DC power supply signal ground
