I’m still recommending a not-as-obsolete amplifier ICs. It’s running about 0.

Sign up or log in Sign up using Google. As I increase the voltage, the ticking goes louder. Post as a guest Name.

There’s literally tsa2009a out there which aren’t as terrible. They are really brand new. It’s a 30W 5A power supply. When I connect both speakers to one channel, even at bigger volumes, it goes just fine. Home Questions Tags Users Unanswered. I’ve built this according to the schematic provided in the images, but I’ve changed the capacitor connected to VCC and GND at pin 9 of the IC to uF and uF with no change I’ve done this because of my lack of capacitors at home.

I’ve bought a brand new TDAA IC in my local electronics tra2009a and all the extra components needed from the schematic, which is provided work this post.

You can either get a stronger source of power more Ampere! There’s nothing comparably good about it. Again, the IC is positively ancient. Go to the website of the former manufacturer of the TDAA it’s http: The datasheet tda2009 like it’s from the mids, at the very least. Or combine any of these measures – especially since the tdaa has been declared obsolete by the last major manufacturer ST for a while now, it’s very likely you’ll find better amplifier ICs. It’s nice that you know your seller personally, but he’s selling you ICs that are marked as “obsolete” at digikey, mouser and other larger retailers, and that the original manufacturer ST doesn’t even list anymore.

When I start about 2. More likely not even in the last 25 years.

It might sound like you hit the “loudness” button on an 70’s stereo. EBay from China is always a bad idea.

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. 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. Anyway, is it a good idea to find an AB amp on www.

EDIT See my other answer. Even if DIY audio enthusiast often swear by some older amplifier designs, this IC is simply not worth using in the year Try the usual retailers – mouser, digikey, element14, adafruit You’re probably just overloading your power supply with two speakers. It doesn’t have any undervoltage detection, so it’s tda22009a surprise that. I’d claim “it goes just fine” is not really true.

He probably has a stock or an extremely cheap source of obsolete parts and is trying to make tda2009s with inferior products. When I rise txa2009a again to about 7V, the sound is really good, but one of the speakers starts to do that tick tick tick Dj Sushi 18 5.
