Part Number: TPA3123D2EVM Hi Audio Team,
The TPA3123D2EVM using shield inductors for L1 and L2 (A7503AY-220M). These have become EOL and my customer is looking into options for replacement.
Do these 22uH inductors need to be shielded? If so, what…
Hi Michael,
I think you could find this info in the TPA3123D2 EVM user's guide:
And the following picture shows the cable which we usually use for the connection between the board and PC.

Part Number: TPA3123D2 Dears Sirs, I have a problem with TPA3123D2 amplifier. It worked ok, but at this moment when I rise input signal level, the output is cut-off, current consumption latch in 170mA and the chip start hot. I thought the speakers was…
Hi, Ali,
Sorry about that! We have posted the gerbers in the TPA3123D2EVM Product Folder, and the PCB is the same between the two ICs.

I just ordered a TPA3123D2EVM through digikey to test at low frequency, but now I realize that the application diagram in its spwc sheet, and its EVM, have 470 uf DC blocking capacitors on the output, which has a large impact on the low freq response…

The TAS5613 and TAS5630 are capable of delivering considerable power for a distributed 25 VAC audio system. Are these good candidates for achieving…
Hi Yang,
Let me add some comments below:
LC filter can be included, as you mention it would take signal into sine-like wave based on the input signal. No problem with this. Use of filter, either LC or ferrite+capacitor depends on the application…
