Maxim Alternatives for the National Semiconductor LM4670

National Semiconductor LM4670

Benefits of the MAX9700 over the LM4670:

• Higher efficiency (92% vs. 87% for the LM4670).
• Lower distortion (0.01% THD+N vs. 0.30% for the LM4670).
• Lower EMI radiation (selectable switching frequencies and spread spectrum modulation help reduce EMI vs. fixed switching frequency for the LM4670).
• Uses internally fixed gain to save passive components (3 external components required vs. the 5 required by the LM4670).

Benefits of the LM4670 over the MAX9700:

• The LM4670 has adjustable gain that allows for more flexible gain configuration than fixed gain.
