    The TPA32xx Class-D audio amplifier family delivers tremendously high audio performance with less than 0.01% THD+N to clipping. The extremely high level of audio performance makes this device an ideal candidate for today’s high resolution and high fidelity audio applications where previously, only Class-AB amplifiers could deliver the performance.Since the TPA32xx family is an analog input close

    The TPA324x and TPA325x family of parts (TPA3244, TPA3245, TPA3250, TPA3251, and TPA3255)comes equipped with functionality to simplify systems with multiple Class-D amplifiers. Class-D amplifiersuse pulse-width modulation (PWM) switching (450 kHz – 600 kHz), which are discrete packets of energy,to deliver large amounts of power with very high efficiency. However, issues can arise if multiple

    This application report provides design information for an external load diagnostics circuit to detect andidentify electrical faults between the output of an audio amplifier and a target speaker. While theTPA3111D1-Q1 class-D amplifier is used as an example in this application note, this design methodologyis relevant for most class-D amplifiers to provide external fault diagnostics.
