(a) Design the circuit shown in Figure P15.72 such that \(v_{O 1}=-v_{O 2}\) and the voltage gain \(A_{v}=v_{L} / v_{I}=25\). The largest resistor value is to be limited to \(100 \mathrm{k} \Omega\).

(b) If the peak value of each op-amp output voltage is limited to \(\pm 12 \mathrm{~V}\) and the peak current that each op-amp can source or sink is limited to \(1.2 \mathrm{~A}\), determine (i) the maximum average power that can be delivered to the load and (ii) the optimum load resistance.

(c) If \(R_{L}\) is twice the value found in part (b), what is the maximum average power that can be delivered to the load?
