National Semiconductor LM4663

Benefits of the MAX9753 over the LM4663:

  • Lower THD (0.03% vs. 0.2% speaker, 0.03% vs. 0.15% headphone) than the National LM4663
  • Higher PSRR than LM4663 (80dB vs. 44dB headphone; 77dB vs. 44dB speaker)
  • Lower supply current (18mA vs. 35mA speaker)
  • 2 pin-selectable gains vs. one for LM4663
  • DirectDrive eliminates the 220µF caps required by the LM4663
  • Integrated headphone sense circuits (LM4663 requires external components)
