Headphone amp

audioPT · 28th September 2004, 03:34 PM

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 ?

Hi!

Main specs:
- Impedance - 120 Ohm
- Frequency response - 12 to 38500 Hz

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,

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
