  • TPA3131D2: TPA3131D2 output filter

    TI Thinks Resolved
    Part Number: TPA3131D2 Hi, TPA3131 is filter free class D audio PA, is it ok if I use TPA3131 without LC filter and ferrite bead filter? And is there any requirement on minimum capacitor need to place on the speaker line? Best regards, Zoe

  • TPA3131D2: Can PLIMIT be changed dynamically?

    TI Thinks Resolved
    Part Number: TPA3131D2 Hi Team, We would like to adjust power limit dynamically with the TPA3131D2. Can we do it by changing the voltage on the PLIMIT pin on the fly? Thanks! Roy

    TI Thinks Resolved
    Part Number: TPA3131D2 Hello sir! I designed used by TPA3131D2 Audio AMP. My schematic is below that And FAULTZ pin is direct connected with SDZ pin and connected to VCC_AMP Power with 100kohm resister. But Audio is not display and FAULTZ…

  • TPA3131D2: About the unused input pin in a single-ended application

    TI Thinks Resolved
    Part Number: TPA3131D2 Hi Team, I have one question on the statement below. "In a single-ended input application, the unused input should be ac grounded at the audio source instead of at the device input for best noise performance" If ac grounding…

  • TPA3131D2: GVDD external current limit

    TI Thinks Resolved
    Part Number: TPA3131D2 Can the datasheet conditions of <200uA be drawn externally through the PLIMIT resistor? The datasheet recommends 100k ohm resistors, but can 40k ohm range be used as long as the external current is below 200uA?

  • TPA3131D2: Overcurrent testing

    Resolved
    Part Number: TPA3131D2 How can I test the 3.4A typical overcurrent trip point on the device for an over current fault? I have tried an OUTNx short to GND and a short across OUTNL/R (load) without being able to create a FAULTZ low. Please advise how to…

  • TPA3131D2: MONO config, can output floating?

    TI Thinks Resolved
    Part Number: TPA3131D2 Hi Team, Customer only need one channel from TPA3131, can we float the output pins? (BSPL/ BSNL/ OUTPL / OUTNL) And short INNL and INPL directly to the GND. Anything else needs to do? Thanks! Andrew

  • TPA3131D2: TPA3131D2 input and control sequence

    Resolved
    Part Number: TPA3131D2 Hi team, Codec output differentially to left channel and Tone voice is output by HPR single terminal in right channel. When Tone tone works alone, there will be obvious POP tone (Figure 2). We try to delay PA_Mute for 60 ms…
