hello friends recently i have started a project of make head phones so in that case i needed an amp but the amp which i got on internet is not working with my pc can any please help me out .i am using ic tda2030

The pinouts from the TDA2030 datasheet do not seem to match your schematic.

Once you get the pinout right, that is an awful lot of power to run headphones.

Thanks a lot friends

agreed, and I would be surprised if the chip still works with 26 or so volts pimped into its input pin

uh huh 20+ W into headphones will deafen you

Can anyone share an appropriate circuit for headphones in which I can use tda2030 ic and please ...... Can any Tell me a way to check the ic tda2030 before I start with the circuit . Thanks in advance.

Thank you I will go up with your advise

forget the TDA2030 its way to powerful for headphones

look at something like this ....

hello guys since as you told that to not use tda 2030 as it wont work with headphone then where this amp is working as i have already built the circuit on circuit board . i dont want the desolder away the circuit.

No one said the TDA2030 would not work for driving headphones, just that it was an inappropriate choice because it was meant to drive speakers rather than headphones. Of course, your particular TDA2030 might not work if you had fried the chip by hooking up the pins wrongly. In that case you would need to desolder it anyway.
