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.
