    Hey dude, your speaker is not connected correctly. Left terminal has to connect to pin 4 of left ic. Pin 2 is the inverting input.

    • @TechTalkSwarup
      @TechTalkSwarup  3 ปีที่แล้ว

      Pin no 4 is actually pin no 2.. the pin numbers are inverted for this diagram.

    Dear friends this circuit diagram is worng. Tda2030ic 1 pin invering input. 2 pin is Non inverting input .3 pin is negative supply . 4 pin is output. 5 pin is +supply. But this circuit 1 pin is supply. 5 pin ground. It worng real 1pin input. 5 pin is positive supply. Do not use this circuit.

Your subscribes a another tda 2030 circuit do this pin number method what happened U know. This circuit correct. But method is wrong.

    swarup sir , i have 2.1 2050 ic audio board. Two ic using for music and 3rd ic for subwoofer. I want much more extra gain for subwoofer,can I connect 3rd ic audio in (pin no 1) to another ic audio in ( pin no 1 bridge mode) using jumper wire, is that the way to boost sub ???? or ic' s gone a blast 🤔

      Yes this is possible. But it will take a huge effort.
      Because the circuit is not designed for bridge connection.
      To create another circuit board would be much easier.

      The speaker used has nothing to do with the ic temp as long its impedance matches the amp's output impedance or is higher. In the case that it's a 2x203x BTL configuration, speaker impedance must bei 8Ohms or up. You can even drive a 500w sub with the circuit as long it's 8ohms or up

      @@TechTalkSwarup careful! TDA2030 must not be used with 4ohm load in BTL configuration! And with +/-12V into 8ohms it's not even close to 40W. Referring to the datasheet it's 28W with +/-14V. It MAY be that you can get roughly 40W into 4Ohms but only with the max supply of +/-18V and a terrible THD and heat dissipation but I assume that heat would rise much more than output power.

      2050 jada voltage pai chalta hai....
      Aap 2030 ko change karke 2050 laga sakte ho.. par 2050 ko change karke 2030 nahi laga sakte ho .. uske liye kam volt ka transformer lagana parega....
