Default Do I want to much? Somebody help me!

Hi all ;

I need an amplifier a close as possible to specs below.

1) Battery powered (1.2V per channel only, but I am ready to use DC-DC converters)
2) 2 Watt Peak out put
3) Class A if possible (I know it will eat the battery)
4) Simple and Small (will fit in a very small case)
5) It must accapt both lin out & headphone out.

I will be very please if some one can point me the right direction.


best regards
Mertol

It is possible to build a headphone amp with 2.5V~3V

To get 2W at 4 ohms you will need more like 5V

Most headphones these days seem to be about 32 ohms, so you will need more like 3 cells to get 50mW output.
