EAMP08 RC headphone amplifier. TPA6120 based.
 
Hello all,

Some times ago, i have designed a little headphone amplifier for me and some of my audio enthusiast friends. It's name is EAMP08.
A that time, i was thinking built some others but i had never find the time to finish them.
So now, i have many bare PCB of this project and also all parts for about ten.
I precise that this is not a commercial project.

The main features are :
_Texas Instruments TPA6120 headphone output driver.
_Analog Devices AD8599 input buffer.
_Cirrus Logic CS3310 digital volume control.
_RC5 programmable remote control for mute and volume.
_115 or 230Vac input voltage.
_Line and line out (to control volume of power amplifier).

Below, some documents and photos of this project.
EHAMP08 functional synoptic.
EHAMP08 Schematic.
EHAMP08 Manual.

If DIYers are interested, i can sale bare PCB (with the TPA6120 already soldered), and also parts kit including drilled enclosure.
Note that the amplifier include a micro-controller that need a PIC IC programming hardware !(like PICkit or ICD2..)

The price for one PCB including the TPA6120 pre-soldered and the worldwide shipping will be 15.
I will send also with all bare PCB, a full zipped folder where you will find all you need to build the project.
If you look for a complete kit including all parts and drilled enclosure, please PM me.
Regards.

If you have any question about the design, don't hesitate !

Frex.




Regards.

Looks very nice, and if I didn't have a million unfinished projects already I would be very interested :)

One question: Where did you get the lens for the IR diode?
