It is required to use the LM380 power amplifier to drive
Chapter 11, Problem 11.50(choose chapter or problem)
It is required to use the LM380 power amplifier to drive an 8- loudspeaker while limiting the maximum possible device dissipation to 1.5 W. Use the graph of Fig. 11.38 to determine the maximum possible power-supply voltage that can be used. (Use only the given graphs; do not interpolate.) If the maximum allowed THD is to be 3%, what is the maximum possible load power? To deliver this power totheload what peak-to-peak output sinusoidal voltage is required?
