Consider the op-amp described in Problem 14.1. In addition, the maximum output current of the op-amp is \(\pm 15 \mathrm{~mA}\). The resistors used in the configuration are \(R_{2}=160 \mathrm{k} \Omega\) and \(R_{1}=2 \mathrm{k} \Omega\). A load resistor \(R_{L}\) is also connected from the output terminal to ground.

(a) If \(R_{L}=1 \mathrm{k} \Omega\) and the output voltage is \(v_{O}=4.5 \mathrm{~V}\), what is the output current of the op-amp and what is the value of the input voltage?

(b) Determine the minimum value of \(R_{L}\) that can be used for \(v_{O}=-4.5 \mathrm{~V}\).

Data From Problem 14.1:-

An op-amp is connected in an inverting amplifier configuration with a voltage gain of -80 and is biased at \(\pm 5 \mathrm{~V}\). If the output saturates at \(\pm 4.5 \mathrm{~V}\), what is the maximum rms value of an input sine wave that can be applied without causing distortion in the output signal?
