Someone have experience with this D class chip?
How good SNR, THD+N at 0 gain volume setting for example? I am interested in -8db, to 0db gain settings.
All this for high sensitivity speakers. The power i need is some 0.1W-0.2W for each channel in 3 way active system. Mid and bass 6 Ohm, HF 4 Ohm.

It has the same Power figure as the 2822 Power amp.
With half Vsupply
Yes, rather un-audiophile since 3-400V and higher are seen in those glowing amplifier
Uuhh...audiophiles used to call It Front End...uhm, now I 'm puzzled...

Well, nobody got the idea in the parallel thread about (very)low Power amplifiers, probably because of the incumbent 10% THD, but the ubiquitous and tiny 2822 might find its use. BTL for the woofer and SE for 'fullrange', as usual 🙂
Wow! 🙂
BTW there are low power amplifiers that do perform excellent. Maybe it is a good idea to select on quality?!

I'm in search now. Ideas? Power i need 30mV - 1500mV, low SNR, low THD+N, zero gain for 3 wy active https://www.diyaudio.com/community/...40-10rs350-need-some-help.393606/post-7281359
Zero gain = no amplifier. I think the setup as thought out is somewhat flaky 🙂
Perhaps the maximum quite low power is not the right parameter to focus on.

Not true. Amplifier gives amperes, watts.
My system needs only 0.1-0.2w per channel.
They are amazing. They sounds like monitors in the near field. But compared to monitors the scene is much larger in width, depth and height. And of course weight, attack. They are big. No problem with midbass, and bass like with any small speakers i have before. Owerall i just wanna "smaller" amplifiers for them.
If your loudspeakers only need less than a Watt then a 5...10 Watt amplifier will work just fine. Chances on distortion are higher with too light amplifiers.
You are right about not needing much power when having high efficiency loudspeakers. Small amplifiers have a lot of benefits, I follow the same ideas and noticed I don't need anything more than 1W in reality. But... one does not need to use full volume when using a 10W amplifier. There is a lot more to choose in this class and of way better quality that that PAM device. 5 ...10W is also still a small amplifier and you'll have the benefits of small (no fan, no heat, small size, low weight) and enough headroom. You may also like low noise and low output impedance, low EMI output. In other words: you might like the specifications of large amplifiers but with lower maximum output power.
If there is no technical reason for choosing light amplifiers then you are making a predefined system choice that will introduce more issues than when you hadn't. So the focus might be on the wrong parameter.

I understand. What amplifier do you recommend?My question is not entirely correct regarding power. But i really dreaming about negative gain amplifier. I am Ok with small gain options too.
I made some question before

I need some advice.

Are they 1.5mm by 1.5mm? 💩 Is it true? I don’t mind, but I can’t solder it myself. 😆 I like parameters of snr and thd+n. Very good, but didn't find info about frequency response.
I imagine my 10" inch bass and 6" inch mid driven by this tiny dot. But from TS parameters all looks ok. Only FR... no info.
The amplifier is filter free so you can expect it to be flat with its frequency response within the audible band and load agnostic.
Good. I got the idea to make 6 channels using these little dots. This idea has not left me since I saw them. 😆 This week I'll look for companies that will print boards for them. I imagine a small board 50mm by 10mm that has 6 litle dots amplifiers. And the wires from this board are thicker than the amplifiers themselves. 🤣
