Working Principles

The TPA3136AD2PWPR is a Class-D audio amplifier that uses pulse-width modulation (PWM) to amplify audio signals efficiently. It converts the input analog audio signal into a digital PWM signal, which is then amplified by the power stage to drive the speakers. The high efficiency of Class-D amplifiers reduces power dissipation and allows for smaller heat sinks.
