amplifier – TDA output DC offset – Electrical Engineering Stack Exchange

The TDA was designed for an 8 ohm unit. Curd the word ‘offset’ usually refers to the steady-state DC level – ie: By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

It’s a high-gain amplifier and might be oscillating if you built tda77052 circuit on a breadboard.

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. The peaks seem to get distorted.

Guill 2, 4 5. Tdx7052 did you do with both outputs the circuit diagram doesn’t show? The nF has to be ceramic for a reason low ESR.

I should also mention that this is my first circuit on a breadboard, so it could be causing problems too. I’ll try with a PCB and a nF capacitor next.

First problem is that the amplifier won’t work on voltages above 3. 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.

I’m feeding in 12Vdc and the tea7052 is drawing around mA, which makes for 1.

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 tda7502 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. If the IC is getting hot, well it needs to be mounted to a heat sink. Now about my problems: Home Questions Tags Users Unanswered. It sounds like you have a perfectly good amplifier that is tda7025 missing a heat sink.

You can measure the sound card’s output impedance, but it’s probably low enough to not matter. Sound cards have a low impedance output, so 10k log will be fine.
