Maxim Alternatives for the National Semiconductor LM4949

National Semiconductor LM4949

Benefits of the MAX9775 over the LM4949:

• 3D sound engine on speaker amp
• Direct Drive receiver amp, Direct Drive headphone amplifier increases dynamic range over the LM4949's Output Capacitor-Less (OCL) drive and decreases ESD susceptibility
• Highly configurable inputs
• Class D amplifiers emit very low EMI due to Active Emissions limiting (AEL) circuitry

Benefits of the LM4949 over the MAX9775:

• The LM4949 has a smaller package, 2.68mm x 2.68mm vs 3mm x 3mm, and lower typical supply current of 13mA at V_DD = 5V
