Chapter 15, Problem D15.73P

(a) Design the circuit shown in Figure P15.72 such that ${\upsilon }_{O1}=-{\upsilon }_{O2}$ and thevoltage gain $A_{\upsilon }={\upsilon }_L/{\upsilon }_I=25$ . The largest resistor value is to be limited to $100\text{k}\Omega$ . (b) If the peak value of each op−amp output voltage is limited to±12V and the peak current that each op−amp can source or sink is limited to 1.2 A, determine (i) the maximum average power that can be delivered tothe load and (ii) the optimum load resistance. (c) If $R_L$ is twice the valuefound in part (b), what is the maximum average power that can be deliveredto the load?
