  • TPA3111D1: Series Inductor Selection

    Resolved
    Part Number: TPA3111D1 Hi team, We are looking to use the TPA3111D1 in our design but are wondering what inductance to use on the output pins. Looking at page 17 of the TPA3111D1 datasheet, we are seeing 33uH inductors for an 8ohm speaker and 15uH inductors…

  • RE: TPA3111D1: Part works very well except for intermittent start-up with a dc output that self-corrects to zero after 10 to 20 seconds.

    Thanks for the reply, Peter. We are running PVCC at 9 volts. We've added an external H-Bridge to provide the needed current gain for driving 5 amps rms periodic sinusoidal waveform into less than 1 ohm load. The lower the PVCC voltage, the higher our…
