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 - TPA32xx Analog Input Grounding for Single Ended InputsPDF, 79 Kb, File published: Aug 26, 2016

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 - LC Filter Design (Rev. A)PDF, 1.6 Mb, Revision: A, File published: Nov 9, 2016

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.
