TAS6424-Q1: Detailed PBTL operation

Part Number: TAS6424-Q1
Other Parts Discussed in Thread: TAS5414, TAS6424

Hello Expert,

I think this is fundamental question but I'd like to confirm detailed PBTL operation.
We need to connect CH1P and CH1N through LC filter and connect CH2P and CH2 as well for archiving PBTL operation.
Does this mean CH1P and CH1N output same phase signal and become Negative output Side and CH2 side output positive signal as same as CH1 side?

Hello Kazuki,

Just to confirm, this is how you are connecting, correct?

All the best,
Carolina

Hello Carolina,

I'd like to ask about the detailed operation, it is not connection.
I think Out_1P and OUT_1N output same signal as negative side and Out_2P and OUT_2N output same signal as positive side. Then Out_1 and Out_2 achieve PBTL operation. Is this correct.

Because, as I remember, previous gen device of TAS5414's output configuration is connecting same phase output(as like as connecting out_1p and out_2p) but new device of TAS6424's configuration is changed. So I'd like to confirm the detail of output signal with TAS6424.
I understand best way of confirming this point is measuring waveform but unfortunately I cannot measure it due COVID-19. So I ask you.

Sorry for bothering you but would you answer it?

Best regards,
Kazuki Kuramochi

Hi Kazuki,

TAS5414 is not similar with TAS6424.

Please refer the reference design in datasheet.
