Rework Example 5.11 using the nonideal op amp LM324 instead of uA741.
Example 5.11:
Using Schematics, we draw the circuit in Fig. 5.6(a) as shown in Fig. 5.35. Notice that the positive terminal of the voltage source vs is connected to the inverting terminal (pin 2) via the 10Ω resistor, while the noninverting terminal (pin 3) is grounded as required in Fig. 5.6(a). Also, notice how the op amp is powered; the positive power supply
terminal V+ (pin 7) is connected to a 15-V dc voltage source, while the negative power supply terminal V- (pin 4) is connected to -15 V. Pins 1 and 5 are left floating because they are used for offset null adjustment, which does not concern us in this chapter. Besides adding the dc power supplies to the original circuit in Fig. 5.6(a), we have also
added pseudocomponents VIEWPOINT and IPROBE to respectively measure the output voltage vo at pin 6 and the required current I through the 20-kΩ resistor.
