27 gru 2006 · This is my LM4562 based preamplifier. Noise free and transparent sound - this is what I can say after first tests. Output offset voltage (even without DC blocking caps) - about 1-3mV. This PCB can be used for every dual op-amp. I used R3,R9: 2k, R4,R10: 680R. schematic.
The LM4562 audio operational amplifiers deliver superior audio signal amplification for outstanding audio performance. The LM4562 combines extremely low voltage noise density (2.7nV/√ Hz ) with vanishingly low THD+N (0.00003%) to easily satisfy the most demanding audio applications.
