This would apply to the general case, but you specifically undervolt the IC. Some larger seller has a large stock of them.

He probably has a stock or an extremely cheap source of obsolete parts and is trying to make money with inferior products. It might sound like you hit the “loudness” button on an 70’s stereo.

There’s literally thousands out there which aren’t as terrible. When I connect both speakers to one channel, even at bigger volumes, it goes just fine. The datasheet looks like it’s from the mids, at the very least. Or combine any of these measures – especially since the tdaa has been gda2009a obsolete by the last major manufacturer ST for a while now, it’s very likely you’ll find better amplifier ICs.

Go to the website of the former manufacturer of the TDAA it’s http: Yeah, then you reduce the load impedance, and thus, the voltages that the transistors can supply get lower, and your sound gets compressed to a smaller voltage range.


You’re probably just overloading your power supply with two speakers. You can often get them for free as samples, or for little money at online retailers. Home Questions Tags Tda22009a Unanswered.

It doesn’t have any undervoltage detection, so it’s no surprise that When I start about 2.

Even if DIY audio enthusiast often swear by some older amplifier designs, this IC is simply not worth using in the year As I tdaa2009a the voltage, the ticking goes louder.

Is there any way to stop the weird ticking? When I bump it up to about 4V, the sound it totally distorted. And I specifically mentioned Ampere so that you don’t increase the volts Increase the voltage to at least 10V. The amperes are just fine, check out the video.

Don’t just buy anything your local seller recommends. I’m running the IC 8V. When I rise it again to about 7V, the sound is really good, but one of the speakers starts to do that tick tick tick It’s nice that you know your seller personally, but he’s selling you ICs yda2009a are marked as “obsolete” at digikey, mouser and tda2009x larger retailers, and that the original manufacturer ST doesn’t even list anymore.

I don’t want to blow up my speakers. I’ve actually requested the IC from my seller, because I thought that it is some kind of good quality for a low price, as I’m quite a beginner in electronics.

If I connect a speaker 8 ohm, about 10W to the right input or the left input, the sound is just great. When I connect it, it still does that ticking sound and the music is quite distorted.

Anyway, is it a good idea to find an AB amp on www. I do personnally know the seller and he sells a lot of these every day, so he has to buy new one like every week or so. EDIT See my other answer.
