Maxim Alternatives for the National Semiconductor LM4910
National Semiconductor LM4910
Benefits of the MAX9722 over the LM4910:
Much better THD+N performance (0.009%, vs. 0.3% for LM4910).
Higher output power (130mW, vs. 35mW for LM4910).
Superior click and pop performance compared to the LM4910.
Maxim's DirectDrive architecture allows the headphone jack to be biased at GND, not VDD/2. This prevents ground current from flowing from amp to a line input where the line input is biased at GND.
Higher ESD protection 8kV, vs 2kV.
Greater PSRR performance, -90, vs -70dB for the LM4910.
Benefits of the LM4910 over the MAX9722:
No specific advantages.
