Part Number: TAS5825P
Other Parts Discussed in Thread: TAS5825M, , TAS5825MEVM, PUREPATH-CMBEVM,

I have made many boards for TAS5825M.

Can I simply put TAS5825P to this boards without any modification?

Thanks for reply

Hello Jiri,

The device's are pin to pin but whole value proposition of the TAS5825P is the Hybrid-Pro algorithm and there is a Hybrid-Pro feedback pin that's supposed to be connected to the DC-DC Converter so HW modification would be needed there. The firmware between the TAS5825M and the TAS5825P is different so you couldn't use the same TAS5825M process flows on a TAS5825P as it may not function properly and could cause issues with the device.

You could bypass the Hybrid-Pro pin configuration and not use the feature but your process flow would still be limited to the TAS5825P limited flows.

Best regards,

Luis

Hi Luis

Thanks for Your reply.

I'm powering my amplifiers from 19V notebook adapter.

I have only TAS5825M developement board and PPCB and sw plugins for both TAS5825.

I'm using simple process flow 2.0 stereo Housekeeping.

Can You please recommend me a simple solution to switch to TAS5825P process flow?

Many Thanks

Jiri

Hello Jiri,

Can you clarify what are you trying to do? Are you using the TAS5825MEVM, not sure if i understand your question.

Best regards,

Luis

I have hundreds of boards for TAS5825M.
M is not in stock, while P is.
So my question was whether I could simply use P instead of M without hardware changes.
I own PUREPATH-CMBEVM and TAS5825MEVM.
TAS5825P-SW is a supposed plugin for PPC3. He owns one too.
The question is, am I able to debug the TAS5825P with my tools?
Another question is, how does the process flow differ between the M and P versions?
I did not find a process flow for the P version on the TI website, only for M.
I also use GPIO1 for MUTE, in datahseet TAS5825P this pin is used for HybridPro feedback. GPIO1_SEL_Register appears to be the same except for bit 0001, for M is Reserved and for P is HybridPro.
Is this the only difference in configuration?
Please advise me about configuration differences.
thank you very much

Hi Amy

Can You please send me a direct link to your TI store?

If I found TAS5825M page and clik on Order now, I still see out of stock.

thanks

Jiri,

It just went to out of stock again. Supply is tight, so material does not last long in our store.
