Chapter 14, Problem 14.2P

Consider the op−amp described in Problem 14.1. In addition, the maximumoutput current of the op−amp is ±15 mA. The resistors used in the configuration are $R_2=160\text{k}\Omega$ and $R_1=2\text{k}\Omega$ . A load resistor $R_L$ is also connectedfrom the output terminal to ground. (a) If $R_L=1\text{k}\Omega$ and the output voltageis ${\upsilon }_O=4.5\text{V}$ , what is the output current of the op−amp and what is the valueof the input voltage? (b) Determine the minimum value of $R_L$ that can beused for ${\upsilon }_O=-4.5\text{V}$ .
