Default Headphone amp

Hi!

Is this TPA4411: 80-mW Capless Stereo Headphone Driver good enough to listen music in the sofa, with a good 'scotch' in one hand and a 'Monte Cristo' in another?

And this in my head?

Or must I make an amp with FET?

"The TPA4411 is ideal for small portable electronics where size and cost are critical design parameters."

I don't think this is a highquality part. THD of 0.08% for 40mW ?
I think you can do much better with few discrete parts...
And if it's for homeuse only, try a real ClassA. You don't need FETs
for building a headphone amplifier.
How many ohms has your headphone ?

almost any music goes better with a Monte Christo and a single malt scotch -- TI has some very low THD headphone amps -- request samples from them (they usually send two.)

Hail!

Hi audiopt

Yes, TI send to you some samples, no problem. Sometimes I use samples to my domestic projects. Some chips realize what you want and is very cheap...

Saturday, we go to the party...

Cheers,
Diogo Almeida

No, they didn't sent me samples... just a email

Yep, I've read the datasheet and found that this is not good for GOOD HEADPHONES...

I'll go discrete Class A .

Yes, Saturday let get party!!!
I'll get there at 11h30

The day to meet our friends never comes

Cheers
