D15.71 Another form of the bridge power amplifier is shown in Figure P15.71. This amplifier has a very high input resistance since the input is to the noninvert- ing terminal of an op-amp. (a) Derive the expression for the voltage gain A, = vL/V1. (b) Design the circuit to provide a gain of A, = 10 so that the magnitudes of v,l and voz are equal. Let R = 50 kN. (c) If R̟ = 202 and if the average power delivered to the load is 10 W, determine the peak am- plitude of vol and vz and the peak load current. A1 R2 RL R3 A2 Ovo2 Figure P15.71
