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 :" …
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…

Hi team,
I am designing with the attached schematic, is there anything wrong with it? Also, the DC bias voltage of LINP, LINN, RINP, and RINN in this circuit is 1.188V. I thought it would be about 1.4V, but why is it so low?
Also…
Part Number: TPA3129D2 Hi team,
Are there any recommended power up sequences on MUTE pin and SDZ pin of TPA3129D2?
Are there any recommended power down sequences on MUTE pin and SDZ pin of TPA3129D2?
Best regards,

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…
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…

Part Number: TPA3129D2 Other Parts Discussed in Thread: TPA3128D2 Hello expert,
My customer has question for TPA3129D2's maximum output power.
My understanding for the difference between TPA3128D2 and TPA3129D2 is only over current trip point by…
Hi Charlie.
Base on your requirement, you can choose amps like below:
Digital input AMP: TAS5805M/TAS5825M
Analog input AMP: TPA3129D2/TPA3116D2
You can choose other chips that you think are better through our official website.
