This project is the ideal solution for high output, high performance high fidelity stereo head phone amplifier. The project consists of Op-Amp LME498720 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

    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?
