DirectDrive technology: no output capacitor required, vs. the large DC-blocking capacitor required by the LM4809; improved low-frequency response; reduced click-and-pop, smaller size; and lower cost.
Outputs up to 80mW into a 32Ω load vs. 50mW from the LM4809.
Higher PSRR (92dB @ 1kHz vs. 72dB @ 1kHz for the LM4809).
Benefits of the LM4809 over the MAX4410:
The LM4809 has lower supply current (1.1mA vs. 4mA).
The LM4809 can operate from a higher supply (5.5V max vs. 3.3V max).
