Put it on a PCB.

That way it is possible to do without the output capacitor saves money and yda7052. When I set input voltage to say mV, the output volume is really low, but there’s no interference. All of your parameters mA for bias current for bridge tda052 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.

It must be as close as possible across the power supply of the amplifier IC.

So, the input is being driven with a signal generator with the td7052 displayed. So far I have been tsa7052 to achieve amplification, with a little distortion.

And here are the input and output waveforms Yellow waveform taken at pin 8, with reference to system ground: Try a few mV input. My problem is that I’m observing a large DC offset at the audio output, and the IC is getting very hot. And here are the input and output waveforms Yellow waveform taken at pin 8, with reference to system ground:.

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. Home Questions Tags Users Ta7052. That’s how a bridge output works. So where do I start fixing this?

The nF has to be ceramic for a reason low ESR. Here’s the effect of increasing volume on a sine wave: Try putting a pot on the input, as a volume control. Sound cards have a low impedance output, so 10k log will tsa7052 fine.

The specialty of the TDA is that fda7052 don’t have one output for a load based at GND but two complementary outputs with the load between the outputs.

Here is my circuit: Why are you using a 50 ohm speaker? Guill 2, 4 5. What did you do with both outputs the circuit diagram doesn’t show? I’m feeding in 12Vdc and the amp is drawing around mA, which makes for 1. The gain is set to 20dB with pin 4 being driven at 1Vdc.

I also used nF electrolytic capacitor, since I don’t have any ceramic at the moment.

If the chip still overheats, it could be faulty. The TDA was designed for an 8 ohm unit.

Curd the word ‘offset’ usually refers tda052 the steady-state DC level – ie: The potentiometer fixed the problems with power supply voltage.

If the IC is getting hot, well it needs to be mounted to a heat sink.

I already know that the speaker and the amplifier can work well together, because they were salvaged from another circuit. First problem is that the amplifier won’t work on voltages above 3. I’ve never had any problems with the TDA Leonardo Rossi 80 8.

I should also mention that this is my first circuit on a breadboard, so it could be causing problems too. Sign up using Email and Password.

Adding a capacitor tdw7052 makes it an AC short. 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.

You can measure the sound card’s output impedance, but it’s probably low enough to not matter. I’ll try with a PCB and a nF capacitor next.
