Part Number: TPA3255 Other Parts Discussed in Thread: TPA3251 , TPA3251EVM , Hi everyone,
I'm developing a very small amplifier for selfpowered speakers. My problem now is Heat! The outputfiltercoils are running extreme hot in a short time ( 100°C…
Hi Darren,
You can if you include a single-ended to differential op-amp configuration. I'd recommend looking at the TPA3251EVM to see how we do it.

Part Number: TPA3251 Hi Team,
I use TPA3251EVM and test its THD vs. freqnency performance, but my test result is really higher than datasheet description, could you help to check if it is normal? thanks.
PVDD=36V, SE input, BTL, 4ohm load, output…
Hi Jerry,
Funny you say this. I changed out the NE5532 on the TPA3251EVM a couple of years ago with the OPA1678 device. There should be no problem switching out the op-amps. For the resistors, changing to a 2kohm resistor shouldn't cause any issues…
Hi Justin
You can open the pcb latout file using ALTIUM DESIGNER or PROTELL 99SE or another tools, the file is ok.
We connnet the same input audio signal to the TPA3251EVM, we test the CLIP_OTW waveform, it is as same as our PCB, But the EVM don't…
Hi Anatoliy,
TPA3255EVM, TPA3251EVM, TPA3245EVM, TPA3244EVM, TPA3221EVM and TPA3220EVM are all compatible with the SideGig-Guitar Evaluation Module board!
The power supply would have to be one that you have however.
Hope this clarifies things. …
Hi Jiri,
We actually don't sell that board. However we do sell the TPA3251EVM which uses the same class-D amplifier as the TIDA-00874. We also have the TAS3251 and an EVM for that device if you need a digital input with the same amount of output power…
Part Number: TPA3251 Other Parts Discussed in Thread: TPA3255 , Hi,
Could you please provide TPA3251EVM and TPA3255 EVM test report to show TPA3251EVM and TPA3255 EVM PBTL mode can support 350W and 600W output respectively?
Best Regards
Sean …
Hi John,
For inputs C and D you would want to ground them if they are not in use. The information regarding setup configurations can be found here: http://www.ti.com/lit/zip/slac735 .
Regarding the outputs to C and D, the only thing you need connect…
