12 Figure P15.72 shows an audio amplifier using two identical op-amps con- nected in a bridge configuration. (a) Derive the expression for the voltage gain A, = vL/vr. (b) Design the system such that |voil= lvo2l = 12v- The largest resistor value is to be limited to 120 k2. (c) If RL = 252 and the peak op-amp output voltages are limited to +8 V, determine (i) the max- imum average power that can be delivered to the load and (ii) the peak cur- rents that each op-amp must source or sink.
