And here are the input and output waveforms Yellow waveform taken at pin 8, with reference to system ground: Try a few mV input. Guill 2, 4 5. The gain is set to 20dB with pin 4 being driven at 1Vdc.

I’m feeding in 12Vdc and the amp is drawing around mA, which makes for 1. My problem is that I’m observing a large DC offset at the audio output, tdx7052 the IC is getting very hot. I should also mention that this is my first circuit on a breadboard, so it could be causing problems too.

Now about my problems: Home Questions Tda7025 Users Unanswered. Sound cards have a low impedance output, so 10k log will be fine. That way it is possible to do without the output capacitor saves tva7052 and space.

Here’s the effect of increasing volume on a sine wave: I also used nF electrolytic capacitor, since I don’t have any ceramic at the moment.

I’ve never had any problems with the TDA It sounds like you have a perfectly good amplifier that is just missing a heat sink. 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.

Adding a capacitor just makes it an AC short. Sign up using Email and Password.

It’s a high-gain amplifier and might be oscillating if you built the circuit on a breadboard. Sign up or log in Sign up using Google.

You are probably overdriving the amplifier by txa7052 a sound card for testing. It must be as close as possible across the power supply of the amplifier IC.

How did you measure the output?

Here is my circuit: So far I have been able to achieve amplification, with a little distortion. First problem is that the amplifier won’t work on voltages above 3. Sign up using Facebook. ttda7052

Tdx7052 did you do with both outputs the circuit diagram doesn’t show? Curd the word ‘offset’ usually refers to the steady-state DC level – tdw7052 It appears that the DC offset of the outputs are not “cancelling out” and that’s why the chip is getting excessively hot.

amplifier – TDA output DC offset – Electrical Engineering Stack Exchange

The TDA was designed for an 8 ohm unit. The peaks seem to get distorted. 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. That’s how a bridge output works. 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:.
