Chapter 4, Problem 20P

For the amplifier in Fig. P4.20, the maximum value of $V_S$ is $\text{2 V}$ and the op-amp can deliver no more than 100 mA.

(a) If $\pm \text{10 V}$ supplies are used, what is the maximum allowable value of $R_2$?

(b) Repeat for $\pm \text{3 V}$ supplies.

(c) Discuss the impact of the supplies on the maximum allowable gain.
