TPA3250D2 which pin drawing is correct?

Hi Adam,

sorry you have to design another board. Our EVM is available for TPA3250D2 evaluation as well.

New pcb is not problem, but well that I asked about the pinout before designing.

I made pcb for 2channel BTL TPA3251D2:

I will design pcb for TPA3250 in 4xSE mode.

Hi Adam,

Looks like you did an awesome job with the PCB layout.. What kind of performance are you getting on your PCB in terms of THD+N vs Power? Is it comparable to our d/s or better? Any special reason for using the coil craft for the output filter inductors?

Thanks for sharing!

I think that 3250/3251 have a mirror in in A,B,C,D and out ...

But In a and in b in the 3250 datasheet seem to be wrong.

These pins in the 3250 evm man seem to be OK.

Pls check?

I had no intention to get full catalog output power . I prefer to leave a big safety margin .
The parameters are comparable , except that I'm working on 8Ohm .
Coilcraft coils are available in Farnell (one of my preffered parts source).
But in TPA3250 design, I will use cheaper MSS1207 10uH coil:

Hi Adam,

Once your meeting your desired spec that's most important. Thanks for choosing TPA325x devices. Let us know if you need further assistance.

Hi Dang,

Yes TPA3250D2 is a horizontally mirrored TPA3251D2. The EVM user's guide has the correct pinout info.
