You can measure the sound card’s output impedance, but it’s probably low enough to not matter.

Sign up or log in Sign up using Google. I should also mention that this is my first tda7052 datasheet on a breadboard, so it could be causing problems tda7052 datasheet. The TDA was designed for an 8 ohm unit.

Why are you using a 50 ohm speaker? Sound cards have a low impedance tda7052 datasheet, so 10k log will be fine. Try a few mV input.

I already know that the speaker and the amplifier can work well together, because they tda7052 datasheet salvaged from another circuit. Sign up using Email and Password. Now about my problems: This site uses cookies to deliver our services and to show you tda7052 datasheet ads and job listings.

Unexpected results with TDA I also used nF electrolytic capacitor, since I don’t have any ceramic at datashet moment. It must be as close as possible across the power supply of the amplifier IC. I’ve never had any problems with the TDA So where do I start fixing this?

Ratasheet a high-gain amplifier and tda7052 datasheet be oscillating if you built the circuit on a breadboard. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is tda7052 datasheet to these policies.

Post as a tda7052 datasheet Name. I’ll try with a PCB and a nF capacitor next.

TDA datasheet Archives – Amplifier Circuit Design

The minimal voltage listed in the datasheet tda7052 datasheet 3 V, typical is 6 V and maximum is 18 V, so this looks a bit strange. The potentiometer fixed the problems with power supply voltage.


You are probably overdriving the amplifier by using a sound card for testing. The nF tda7052 datasheet to be ceramic for a reason low ESR.

Tda7052 datasheet the effect of increasing volume on a sine wave: Put it on a PCB. The speaker tda7052 datasheet quiet much more than in the radio I got the amplifier and speaker form and from time to time it seems as if the amplifier is clipping I’m not sure if that’s the right word.

When I set input voltage to say mV, the output volume is really low, but there’s no interference. Try putting a pot tda7052 datasheet the input, tda7052 datasheet a volume control. Questions Tags Users Badges Unanswered. First problem is that the amplifier won’t work on voltages above 3.
