Hi Jay,

Thanks for your interest in TPA3255. The current schedule is late July/ early August. What application you're planning to use TPA3255?

Hi Damian,

Thanks for the reply. I am just an end user. I have the TPA3116 amp already in my system. Want more power so I can get speakers with lower sensitivity. Thanks again.

Thanks Jay!

TPA3251 and TPA3255 are pin to pin compatible, so you can use TPA3251 for now and swap it out with TPA3255 when it's released. If you're designing a board be sure to design for the high voltage capability for TPA3255, which will work of TPA3255. 100V caps for PVDD and the outputs.

Dear Damian,

Is there any update on the timetable for TPA3255? Is the August schedule for mass production going to be met or will there be slippage?

We are prototyping using TPA3251, would it be possible to get "beta" silicone samples for TPA3255 even if there are known bugs to validate our design?

Kind regards Thorsten

Hello Thorsten,

We are on schedule with the TPA3255 release. It should be released before the end of this month as planned.

Damian,

I have a question about the TPA3255 OSC_IOM & OSC_IOP pins.

I presume that if I tie the FREQ_ADJ pin to DVDD (3.3V), then the OSC_IOM & OSC_IOP pins become a differential clock input to the TPA3255.

I plan on feeding a 24.576/40=614.4kHz differential clock into these two pins.

The TPA3255 datasheet does not have much information on the specs of said differential clock.

Would you have any specs on this differential clock (OSC_IOM / OSC_IOP)?

Thanks,

Sam
