5.7 The op amp in Fig. 5.46 has Ri = 100 kΩ, Ro = 100 Ω, A = 100,000. Find the differential voltage vd and the output voltage vo.
Figure 5.46
For Prob. 5.7.

Calculate the differential voltage
Answer to Problem 7P
The differential voltage
Explanation of Solution
Given data:
Refer Figure 5.46 in the textbook for the op amp circuit.
The open-loop gain A is 100,000,
The input resistance
The output resistance
Calculation:
The equivalent circuit of the the given 741 op amp is drawn and it is shown in Figure 1.
Apply Kirchhoff's current law at node 1 in Figure 1.
Simplify the equation as follows.
From Figure 1, consider the expression for the voltage
Apply Kirchhoff's current law at node 2 in Figure 1.
Substitute 100,000 for A and
Substitute equation (1) in (2).
Simplify the equation as follows.
Substitute 1 mV for
From Figure 1, consider the expression for the output voltage
Substitute 100,000 for A.
Substitute
Conclusion:
Thus, the differential voltage
