Part Number: TPA3255EVM Other Parts Discussed in Thread: LM3886 , TAS5630PHD2EVM , TPA3221EVM , TPA3255 , TAS5630 I've designed several Guitar and Bass amplifiers around the LM3886 Cass A/B IC and I check TI website every week hoping for updates for inventory…
Hi Yuval,
The schematic file is located on the TPA3221EVM page. You can download that from there. Here's the gerber files for the TPA3221EVM.

Part Number: TPA3221 Hi,
A customer is going to use TPA3221 by PBTL AD Modulation. He says that his measurement data of TPA3221EVM THD+N is not less than 0.05 percent. And it is worse than Typical Characteristics of the datasheet.
Q: Did the figures…
Part Number: TPA3221 Hi,
The RC passive low pass filter is applied to the input stage on TPA3221EVM, so could you please tell me whether that is necessary ?
Best regards, Kato
Hi Adam-san,
Thank you for the comment.
I cannot verify this symptom as I don't have TPA3221EVM, so could you please double-check whether this symptom is replicated by using the EVM ?
Best regards, Kato
Part Number: TPA3221 Hi,
The output FETs go into a Hi-Z state after the ramp down is complete if /RESET is asserted to low when TPA3221 works normally. Then, TPA3221 cannot return to the normal mode and switching of the PWM output doesn't start if …
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. …
Markus,
That reset circuit works best when the voltages it monitors are the same ones the device uses. For this reason the latest TPA3221EVM (releasing soon) uses the board 5V instead of the 15V on the resistor divider as shown. I would use the same…
