Part Number: TPA3255EVM Other Parts Discussed in Thread: TPA3255 , LMG3522R030 Tool/software: The datasheet mentions to start in reset and then switch to normal after everything is connected and power is supplied. If everything is already connected, can…
Part Number: TPA3255EVM Other Parts Discussed in Thread: TPA3255 Tool/software: In the TPA3255 users guide under section 3.3 (page 7), for the default setting of BTL 2.0, it mentions AP analog input under each line for speaker or resistive load. For example…
Part Number: TPA3255EVM Other Parts Discussed in Thread: TPA3255 Tool/software: Hello,
It would be helpful to have the source design files for the TPA3255 EVM. Please let me know if these are available.

Part Number: TPA3255EVM Tool/software: Hi team,
From the datasheet 'OTW/SHUTDOWN (FAULT)' section of Electrical Characteristics (continued), it says there are internal pullup resistors of 26k for FAULT/CLIP_OTW pins to "To reduce external component…
Part Number: TPA3255EVM Other Parts Discussed in Thread: TPA3255 Tool/software: Hi,
I'm testing the TPA3255EVM and it seems like overtemperature came very fast.
I'm using the PBTL configuration with Single Ended input, without resistances (as explained…
Part Number: TPA3255EVM Other Parts Discussed in Thread: TPA3255 Tool/software: Hi,
Have you seen this module, as configured with the op amp input buffer on the EVM used with a passive preamp section (no gain)? That is how my stepped attenuator will…
Part Number: TPA3255EVM Tool/software: Hi,
Would it be a cooling or performance issue to mount the TPA3255EVM board on edge (on a well supported bracket)? The board would be sitting sideways (like a slotted module in a desktop PC), oriented with the…
Part Number: TPA3255EVM Tool/software: I have been doing some work with a dozen or so TPA3255EVM modules.
On 3 different modules now, C4 ground connection has randomly vaporized immediately after applying +48VDC PVDD at J1.
Each module had been working…
Part Number: TPA3255EVM Tool/software: Hi,
I'm designing a linear power supply for the TPA3255EVM and will be providing close to the maximum Vdc, around 50V. My current design will provide 6 amps @ 50Vdc. The board requires 5-14 amps. Will providing…
