  • TPA3129D2: Confused about analogue power supply & shutdown logic circuitry.

    TI Thinks Resolved
    Part Number: TPA3129D2 Tool/software: Hi I'm quite new to all this. I'll be referencing the TI Datasheet throughout. My confusion stems from the wording on the pin description. For the SDZ pin and other logic pins it reads, "TTL logic levels with…

  • TPA3129D2EVM: TPA3129D2

    Part Number: TPA3129D2EVM Tool/software: Thanks for response. I have few questions: Switching frequency according to table 6 may be 400, 500, or 600 kHz. According data sheet it may be I watched 5.4 Mhz. What is right? Describe please these :" In…

  • TPA3129D2EVM: TPA3129D2

    Part Number: TPA3129D2EVM Tool/software: I checked TPA3129 evaluation board. We need to use it in sync mode. I have changed R7=100k and R5=16, as result voltage on GVDD=5.9V and GAI/SLAVE=5.07V. In this case amplifier must come to slave mode, when switching…

    TI Thinks Resolved
    Part Number: TPA3129D2 We are using a TPA3129D2 and it appears occasionally to start with the wrong gain. When during the power up sequence is the gain voltage sampled ?. From Data Sheet SLOS941C, May 2016, updated Jan 2018 "The gain setting is latched…

  • TPA3129D2: AUDIO AMP

    Part Number: TPA3129D2 Hi The customer currently amplifies the BTL R/L and PBTL Subwoofer under the undistorted sine wave, and both measure the output Vrms~8V. V2/R =8W is acceptable at 12V BTL, but PBTL should be around 16W. How to adjust to PBTL will…
