Hi,

Anyone see an English language datasheet for this IC chip? It's an amplifier audio chip.

It is an interesting chip because it can do 5 watts and it's just a small SMD 10 lead chip.

I am wondering if this can do class D. I know it can do class AB, but because the datasheets I've found are all in Chinese, I can't be sure.

I might want to add a volume control to this chip circuit in a device I have that has this chip to do the audio amplification. I can probably do that without an English datasheet, but I'd also like to be able to read more about this chip also because it has some variable options.

Thanks for any info...

 

Google Translate, or Google Lens, should be able to convert the datasheets to Englsh.

I tried that but I think it's all an image no real text. It's in a pdf file.

Hello,

Thanks. That kind of tells me what I really wanted to know. It does class D. That's probably how they get such high power out of such a small chip. I was guessing that, but I always like to have written verification.

Thanks again
