TDA7294 Amplifier Board

    "tusker" 100 Watt tda7294 mono amplifier board

    100w TDA7294 amplifier board

    100 watts of Hassle free audio power

    New Version of PCB having space for fitting heatsinks easily.


    Now you can fit Many Types of Heatsinks on the PCB or Fit many pcbs on a big heat sink to make 2.1 or 4.1 or 5.1 Amplifier.


    What TUSKER has achieved in this short period is exceptional.

    Tusker is simple, easy to make and delivers high power with many types of speakers.


    You may ask why the name “TUSKER”, after all it is a small pcb.

    What can I say, small number of Tuskers ( Not the Truck, but Elephants ) still roam the forests of our country, they are Majestic.)

    Brief Description of TDA7294 amplifier circuit :-

                                                                       CLICK HERE to download TDA7294 Amplifier circuit diagram 


    The circuit is quite simple, main job of amplification is done by ic U1 and rest are the supporting components.


    Input signal is fed  to pin no.3 (Non Inverting Input) through R1 & C2. R7 defines the input impedance. 


    R2 & R4 connected to Pin no.2 (Inverting input) set the closed loop gain. Changing the value of any one these resistors will change the gain of the amplifier. 


    Pin no.9 (Stand by) - R6 keeps ic U1 in active mode by providing positve voltage.


    Pin no. 7, 13 are positive supply, Pin no. 8, 15 are negative supply and 1, 4 are ground pins. Pin no.14 is the output pin.


    Mute Function - Pin no.10 (Mute) is connected to JP2. To use the mute function replace JP2 with a switch.


     Metal Tab of ic U1 is connected to negative supply internally, so  proper insulation is necessary when fitting ic U1 on heatsink. 


    Compatible / Replacement Part no.with Datasheet download links.*

    • U1  -   TDA7293, TDA7294, TDA7295, TDA7296


                       *Supply voltages and output power vary, please read datasheet carefully.
