I am having TDA2030 with me, i want to make an amplifier but it is not working in multisim..
Please some one help me

Here is the Circuit Diagram

View attachment TDA2030_Audio_Amplifier.zip

I am also attaching the Simulation file

Please Help me
 

Thanks For your help..

Its working now..
But when i apply signal of 0.1V the out put gets clipped... off..

now i have applied a sine wave of 0.01V rms and i am getting output as follow:-

Its working fine for smaller signals

Now i want to measure power...
I measure it as follow:-

Its very less, i need atleast 10W output power, how i can i achieve this in reality..

I am having speaker of 4ohm and 25 Watts
 

Have you tried a higher power supply voltage?

The TDA2030 is a monolithic integrated circuit in
Pentawatt® package, intended for use as a low
frequency class AB amplifier. Typically it provides
14W output power (d = 0.5%) at 14V/4Ω; at ± 14V
or 28V, the guaranteed output power is 12W on a
4Ω load and 8W on a 8Ω (DIN45500).

Thanks for Your Reply.....

But the Supply voltage is already 15V..
I changed the value of resistance in feedback path..
R1 = 1 M Ohm
and
R2 = 500 Ohm

Now i am getting the Output of 4W when my input is around 1.189nW

Is it okay...
I don't know whether it will work physically or not..

I am not getting why it is written in datasheet that its a 14W amplifier ..
Can anyone explain me why it is so..
