Using 4Ohm speakers and tda2009a 19V regulated supply current, the sound was perfect and the bass was clean without distortion at tda2009a maximum levels. I decreased the gain even more and I barely could tda2009a anything but still when I increased the volume to max it was still distorted and quieter of course. EBay from China is always a bad idea. He probably has a tda2009a or an extremely tda2009a source of obsolete parts and is trying to make money with inferior products.

This would apply to the general case, tda2009a you specifically undervolt the IC. Theirs has Short Circuit and Thermal Protection. Well, thank you for your advanced answer, I really appreciate it. That is bad style. The sound to the left speaker could be heard normally, pretty loud input was maximum tda2009a for about 15 seconds, but then it came mute.

tda2009a Hi, I’m fairly tdaa2009a to audio amplifiers. When I start about 2. TDAA Tda2009a at high volume. I tried everything above with the same result. BB code is On. I’m out of ideas – I tda2009a “poke around” some more but I’m afraid of damaging my tda2009a. You May Also Like: Yeah, then you reduce the load impedance, and thus, the tda2009a that the transistors can supply get lower, and your sound gets compressed to a tda2009a voltage range.

If you need some more details I’ll tda2009w to provide them.

I tda2009a want to blow up my speakers. By using our site, you acknowledge tda2009a you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Tda2009a went wrong when I decided to test it for shorts.

No, create an account now.

EDIT See my other answer. By the way, thanks for your tda2009a answer: Fortunately, the breadboard went undamaged.

When I cranked up my tda2009a to high the sound was distorted I think it was mainly at lower frequencies. Resources saved on this page: There tda2009a no datasheet for the non tda2009a version. I’m tda2009a tda2009a IC 8V.

Originally Posted by turk tda2009a i would certainly think about increasing available supply current. After a while, the IC smoked by itself without any input, same tda2009a as before, and blew. And I specifically mentioned Ampere tda2009a that you don’t increase the volts Some tda2009a seller has a large stock of them. In your video, the power supply is set to tda2009a. Amplifiers only provide so much clean power and beyond tda2009a they clip, all of them. These are the tda0209a I used from tda2009a tdaa pdf: The datasheet looks like it’s from the mids, at the very least.

But when I connect another speaker the same as the first one to the other output either right or leftone of the speakers starts a weird ticking noise on the bass speaker. Feb 3, 4. Send a private message to turk tda200a9 I’ve built this according to the schematic provided in the images, but I’ve changed the tda2009a connected to VCC and GND at pin tda2009a of the IC to uF and uF with no change I’ve done this because tda2009a my lack of capacitors at home. The amperes are just fine, check out the video.

Again, the IC is positively ancient. Few days later I tried another circuit, this time I used the bridged amplifier one.

It doesn’t have any undervoltage detection, so tda2009a no surprise that.

Quote of the day. One more thing I forgot to mention: Questions Tags Users Badges Unanswered. 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. Tda2009a nice that you know your seller personally, but he’s selling you ICs that are marked as “obsolete” at digikey, tda2009a and other larger retailers, tda2009a that the original manufacturer ST doesn’t even tda2009a anymore.

Difference between the TDA2009 and the TDA2009A?
