Integrated audio amplifier

摘要: An audio amplifier having an section and a power supply. The supply comprises positive negative section, each of which provides voltage to the inputs amplifier. control circuitry for sections causes output from vary in accordance with amplitude signal so that voltages track components are at predetermined level above below signal, respectively. Each has pair switches open close alternately transmit pulses opposite ends primary winding, secondary winding turn through filter component its respective input section.
