Part Number: TPA6211A1-Q1
Hello experts,My customer is considering an external load diagnostics circuit (especially open detection) for TPA6211A1-Q1. I found a below TI-Design and application note. They are for class-D amplifier but I think it also enable for class-AB amplifier. Is my understanding correct? If it is not, can you provide an external load diagnostic circuit for TPA6211A1-Q1?- TIDA-01529: Figure 11 Diagnostic Circuit #2 Schematichttp://www.ti.com/lit/ug/tidudn3a/tidudn3a.pdf- SLVA824: Class-D Amplifier External Load Diagnosticshttp://www.ti.com/lit/an/slva824/slva824.pdfBest Regards,Fujiwara
I will take a look at this and will answer as soon as possible.
Best regards,Luis Fernando Rodríguez S.

These diagnostic circuits can be used for TPA6211A1-Q1 as well, just make sure to change the supply voltage reference if using Diagnostic Circuit #2 from TIDA-01529, it should be the same as TPA6211A1-Q1 VDD.
