Maxim Alternatives for the National Semiconductor LM4922

National Semiconductor LM4922

Benefits of the MAX4411 over the LM4922:

• The THD+N peformance at Po = 50mW, RL = 32 is 0.003% for the Maxim part as opposed to 0.03% for the LM4922 under same conditions.
• The maximum output offset for the Maxim part is 2.8mV as opposed to 5mV for rthe LM4922. Thus, the click and pop level is better on the MAX4411.
• The quiescent current is typically 5mA for the Maxim part while the LM4922 has a quiscent current of 7mA.
• The Maxim part is available in UCSP and QFN packaging while the LM4922 is available in just the UCSP package.

Benefits of the LM4922 over the MAX4411:

• The LM4922 has a wider supply range of 1.6V to 4.2V as opposed to 1.8V to 3.6V for the Maxim part.
• The LM4922 has a lower maixmum shutdown current of 1.8µA as compared to 10µA.
• The LM4922 has an auto shutdown feature to reduce supply current draw if no input signal is present.
