I’m feeding in 12Vdc and the amp is drawing around mA, which tdq7052 for 1. Sign up using Facebook. Sign up using Email and Password. I also used nF electrolytic capacitor, since I don’t have any ceramic at the moment.

The gain is set to 20dB with pin 4 being driven at 1Vdc. It must be as close as possible across the power supply of the amplifier IC. Adding a capacitor just makes it an AC short.

It appears that the DC offset of the outputs are not “cancelling out” and tad7052 why the chip is getting excessively hot. How did you measure the output? Guill 2, 4 5.

If the chip still overheats, it could be faulty. So, the input is tdz7052 driven with a signal generator with the parameters displayed.

It’s a high-gain amplifier and might be oscillating if you built the circuit on a breadboard. The potentiometer fixed the problems with power supply voltage.

Here is my circuit: Try putting a pot on the input, as a volume control. The nF has to be ceramic for a reason low ESR. The TDA was designed for an 8 ohm unit. 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.

Try a few mV input. Why are you using a 50 ohm speaker?

It sounds like you have a perfectly good amplifier that is just missing a heat sink. Fda7052 problem is that the amplifier won’t work on voltages tca7052 3.

So far I have been able to achieve amplification, with a little distortion. That’s how a bridge output works. Home Questions Tags Users Unanswered. I’ve never had any problems with the TDA Sign up or log in Sign up using Google.

And here are the input and output waveforms Yellow waveform taken at pin 8, with reference to system ground:. Here’s the effect of increasing volume on a sine wave: I’ll try with a PCB and a nF capacitor next. Sign up or log in Sign up using Google.

That way it is possible to do without the output capacitor saves money and space. You are probably overdriving the amplifier by using a sound card for testing.
