Part Number: TPA3128D2EVM Hello,
When probing one of the audio outputs of the TPA3128 with respect to ground (i.e. single ended) while idling, my customer sees a waveform like that shown below. It doesn't look like normal output ripple and we are curious…
Part Number: TPA3128D2EVM Other Parts Discussed in Thread: TPA3128D2 I just received the TPA3128D2EVM and I tried turning the potentiometer, but the gain does not change. Is there a jumper or other kind of setting that is bypassing the potentiometer? I…
Part Number: TPA3128D2EVM Other Parts Discussed in Thread: TPA3128D2 Hi ,
Please clarify about the RC snubber positions in the TPA3128D2 EVM Schematic.
In this schematic , capacitor C2 connected to the line output and Resistor R1 end connected to ground…
Part Number: TPA3128D2EVM Hi SIr,
I need the TPA3128D2EVM schematic and pcb file in Altium Designer for my reference design, could you please send the related file to us? My email address is helen-chen@ti.com
Hello Danilo, There's a multitude of issues i can see and would recommend they look at the TPA3128D2EVM and Typical Applications guide in the datasheet for reference on their schematic.
There's no output LC filter
Fault pin is floating, so can…
Part Number: TPA3128D2 Hello Experts, My customer is testing TPA3128D2EVM and have a question as follows. Would you please answer it? [Question] Customer measured crosstalk but it was -83dB that is too worse than datasheet spec (-100dB). Customer changed…
Hi Alix-san,
Thank you for your reply.
This pop noise was replicated not only on the prototype board but also on the TPA3128D2EVM when adding the resistor attenuator as above. Unfortunately, I don't have TPA3128D2EVM and cannot replicate it. So, could…
Part Number: TPA3128D2 Hi team,
Customer is evaluating TPA3128D2EVM with BTL connection. We are using 4ohm speaker with around 15W at this moment.
According to datasheet, minimum load impedance is 3.2ohm. If we reduce energy to 5W,can the BTL 2ohm speaker…
Hi Keshav,
Could you show me your schematic?
Do you have a TPA3128D2EVM? If so, can you see the same problem if you use the same power supply (12V) to power the EVM?
