Hi-Fi Stereo Headphone Amplifier using LME49600
This project is the ideal solution for high output, high performance high fidelity stereo head phone amplifier. The project consists of Op-Amp LME49720 and LME49600 as output driver. The LME49600 is able to drive 32Ω headphones to a dissipation of greater than 500mW at 0.00003% THD+N while operating on ±12V power supply voltages. The LME49600 is a high performance, low distortion high fidelity 250mA audio buffer. The LME49600 is designed for a wide range of applications and is fully protected through internal current limit and thermal shutdown.
Features
- Supply +/-12V
- Output Load 32Ohms Headphone
- Input Line Level Audio Signal
- Onboard Volume Control

PCB
The circuit board does not match the circuit, Vin and Vee are connected on the right buffer
There is no Vin and Vee in schematic, just +/-12 V and -Ve +Vc
which means no, Vin and Vee are 2 and 3 legs of lme49600 and they are connected on a printed circuit board
Sorry, i was looking on the input/outputs only. I’ve uploaded the bottom layer of PCB, does this clarifies the issue?
No problems, be careful, pcb with errors, I downloaded gerberas, if someone repeats, then will be disappointed … i remake pcb, this my pcb http://radioaktiv.ru/engine/download.php?id=307
