Use VA = 2 V and VB = 3 V with power supply rails of ±18 V. Ask your lab instructor to give the correct pin-out of the 741 if necessary. To obtain the approximate input voltages, use the voltage divider circuit shown below; if you don’t have 30- resistors available, use two 15- resistors in series for each. Some component “tweaking” may be necessary if your particular circuit is an appreciable load on the voltage divider. When connecting the bipolar power supply, make sure the center terminal is connected to the same common ground as the rest of the circuit; otherwise, it will not work properly. 15 30 30 0 2 3 5 V
