The pcb looks like this.
[h=Background]%2[/h]
I have designed a headphone amplifier based on the extremely high performing TPA6120a. The pcb has also a complete power supply with transformers and all.
Interesting features:
- The pcb fits virtually any single opamp
- Room for good coupling caps (if you must or like).
- Input LP-filter if you have problems with RF interference (you should have a filter though).
- High speed and high performance SMD current feedback amp as output stage.
- No global feedback.
- High quality power supply with large smoothing caps and transformers on the pcb.
- Separate voltage regulators for each channel.
- Fits any headphone.
