National Semiconductor LM4811용 Maxim 대체품

National Semiconductor LM4811

Benefits of the MAX9723 over the LM4811:

• Direct Drive technology eliminates the need for the two large 100uF caps that the LM4811 requires on the output.
• Greater output dynamic range (7.2V vs. 5V for the LM4811).
• THD+N 0.005%, vs. 0.5% for the LM4811 (V_DD = 3.3V, P_OUT = 25mW)
• Better PSRR (-87dB at 217Hz vs. -60dB for the LM4811).
• Bass Boost feature increases low frequency output to compensate for small diaphragm speakers.
• Programmed via I²C interface.
• Higher resolution volume control.

Benefits of the LM4811 over the MAX9723:

• The LM4811 has lower supply current (3mA max vs 6.5mA max).
• The LM4811 has better crosstalk performance (100dB vs 80dB).
• MAX9723 can only operate up to 3.6V.
