Is This A AB or D Class Amp?

[Laniakea]

So couple posts back I asked if my amp belongs to what class of amp and you guys told me to check its IC part number online and I did. So HERE it is.

 

Moral of the story is I scanned through the whole document and couldn't find any clues about what class it is Checked the efficiencies too but couldn't decide. Can anyone who understands this stuff help? Thanks :33

LCSC says AB: https://lcsc.com/product-detail/Audio-Power-OpAmps_Anpec-Elec-APA2068KAI-TRG_C11147.html

Thank you so much ^o^ and btw the row below the model number is I guess part number right? Because mine is different soo I guess it is. I'm 200IQ right eheheheh. Just kidding but it'll be nice if u confirm me on that :))

China is a copy cat. If you can find one part with the same part numer APA2068 then it is likely that all manufactures sell AB amplifier under this name with similar performance. The letters after APA2068 are just additional parameter specifying things like packaging, temperature range and so on.

Thanks man :))

Usually class D audio amplifier ICs require an inductor on the outputs (one for each speaker)

 

Class A / B / AB (and a few others) amplifiers require a big capacitor in series with each speaker for output DC decoupling, unless the chip is configured in BTL mode, where two output channels are connected together to a single speaker.

 

You can see the 220uF capacitors on the outputs (on the right side)... so it's NOT a class D amplifier. It's probably a class AB.

Thank you sooooooo much for sharing your knowledge with us man :) I'm quite a nerd about electronics although I'm a newbie so this is very valuable for me thanks :)
