Maxim Alternatives for the National Semiconductor LM4947
National Semiconductor LM4947
Benefits of the MAX9776 over the LM4947:
3D sound engine on speaker amp
DirectDrive receiver amp, DirectDrive headphone amplifier increases dynamic range over the LM4947'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 LM4947 over the MAX9776:
The LM4947 has Nationals 3D engine on its headphone amplifier, and lower typical supply current of 7.6mA at VDD = 5V
