Other Parts Discussed in Thread: TAS5611A Hi Sir:
I have used TPA3123 SE module in my project, and I have designed my schematic reference datsheet and TPA3123EVM. After LOUT LC filter I add audio transformer to boost voltage to110V to connect speaker…
hi
i m using 3211d2 id for amplification bt when i setup all connection it not work.
i used 1uf replace of .68uf and 2 parallel comp of .1uf replace .22uf.
Hi Yang,
