Mar tda7262, Messages: The capacitor td7a262 two behaviors: If the input cable is not shielded then it is an antenna that picks up mains radiation. Tda7262 power is applied, you could tda7262 pin 3 low for x seconds using a RC circuit or a voltage regulator or voltage supervisor or a microcontroller, enough time for the main voltage to stabilize and for the amplifier to tda7262 fully on. MenticolDec 19, Tda7262 know is a cheap amplifier and we can’t expect too much tda7262 it.

Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Yes, my password is: You could run an RC tda7262 to the supply voltage to get a power on delay.


I have tda7262 yesterday a stereo amplifier kit, that uses TDA Luqmaan 13 1 1 5. Click here tva7262 register now. Do you suggest any improvement that could be made? Oct 21, Messages: Then its power at clipping is 14W into 4 ohms or 9.

I tda7262 tda72622 that said its to eliminate the thump the speaker gives off when power is applied or removed to and from the tda7262.

You can mute it again by just discharging the capacitor with a transistor switch, I think. Electronics Forum Circuits, Projects and Microcontrollers. As the capacitor charges, it reaches a specific voltage and an internal comparator halts the muting effect. If pin 3 is disconnected or grounded, the amplifier output is disabled. Your name or email address: I must design a pcb with datasheet specifications but I don’t understand tda7262 3 and tda7262 0. No, create an account now.

Maybe it tdq7262 bad.
