If the chip still overheats, it could be faulty. And here are the input and output waveforms Yellow waveform taken at pin 8, with reference to system ground: The specialty of the TDA is that you don’t have one output for a load based at GND but two complementary outputs with the load between the outputs.

Adding a capacitor just makes it an AC short. 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 subject to these policies.

Why are you using a 50 ohm speaker? All of your parameters mA for bias current for bridge output seem normal and you stated it put out a clean sound, so I do not think anything is wrong-except for a missing heat sink. The gain is set to 20dB with pin 4 being driven at 1Vdc. My problem is that I’m observing a large DC offset at the audio output, tra7052 the IC is getting very hot.

Tda7025 up or log in Sign up using Google. That way it is possible tda70052 do without the output capacitor saves money and space.

So far I have been able to achieve amplification, with a little distortion. Post as a guest Name. Try a few mV input. The minimal voltage listed in the datasheet is 3 V, typical is 6 V and maximum is 18 V, so this looks a bit strange.

Put it on a PCB. If the IC is getting hot, well it needs to be mounted to a heat sink. And here are the input and output waveforms Yellow waveform taken at pin 8, with reference to system ground:.

The potentiometer fixed the problems with power supply voltage. Try putting a pot on the input, as a volume control. When I set input voltage to say mV, the output volume is really low, but there’s no interference.

How did you measure the output? I’ve never had any problems with the TDA So where do I start fixing this? Sign up using Facebook. That’s how a bridge output works. Sound cards have a low impedance output, so 10k log will be fine.

So, the input is being driven with a signal generator with the parameters displayed. The peaks seem to get distorted. You can measure the sound card’s output impedance, but it’s probably low enough to not matter. Sign up using Email and Password.

Here’s the effect of increasing volume on a sine wave: Curd the word ‘offset’ usually refers to the steady-state DC level – ie: It sounds like you have a perfectly good amplifier that is just missing a heat sink. Sign up using Email and Password.

I should also mention that this is my first circuit on a breadboard, so it could be causing problems too. I already know that the speaker and the amplifier can work well together, because they were salvaged from another circuit. The nF has to be ceramic for a reason low ESR. I also used nF electrolytic capacitor, since I don’t have any ceramic at the moment.

The speaker is 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.

The TDA was designed tsa7052 an 8 ohm unit. What did you gda7052 with both outputs the circuit diagram doesn’t show? First problem is that the amplifier won’t work on voltages above 3. Home Questions Tags Users Unanswered.

You are probably overdriving the amplifier by txa7052 a sound card for testing.
