6W, Filterless, Spread-Spectrum  
Mono/Stereo Class D Amplifiers  
General Description  
Features  
Filterless Class D Amplifier  
The MAX9713/MAX9714 mono/stereo class D audio  
power amplifiers provide class AB amplifier performance  
with class D efficiency, conserving board space and  
eliminating the need for a bulky heatsink. Using a class  
D architecture, these devices deliver up to 6W while  
offering greater than 85% efficiency. Proprietary and  
patent-protected modulation and switching schemes  
render the traditional class D output filter unnecessary.  
Unique Spread-Spectrum Mode Offers 5dB  
Emissions Improvement Over Conventional  
Methods  
Up to 85% Efficient  
6W Output Power into 8  
Low 0.07% THD+N  
High PSRR (76dB at 1kHz)  
The MAX9713/MAX9714 offer two modulation schemes:  
a fixed-frequency mode (FFM), and a spread-spectrum  
mode (SSM) that reduces EMI-radiated emissions due  
to the modulation frequency. The device utilizes a fully  
differential architecture, a full bridged output, and com-  
prehensive click-and-pop suppression.  
10V to 25V Single-Supply Operation  
Differential Inputs Minimize Common-Mode Noise  
Pin-Selectable Gain Reduces Component Count  
Industry-Leading Integrated Click-and-Pop  
Suppression  
The MAX9713/MAX9714 feature high 76dB PSRR, low  
0.07% THD+N, and SNR in excess of 100dB. Short-cir-  
cuit and thermal-overload protection prevent the  
devices from being damaged during a fault condition.  
The MAX9713 is available in a 32-pin TQFN (5mm x  
5mm x 0.8mm) package. The MAX9714 is available in a  
32-pin TQFN (7mm x 7mm x 0.8mm) package. Both  
devices are specified over the extended -40°C to  
+85°C temperature range.  
Low Quiescent Current (18mA)  
Low-Power Shutdown Mode (0.2µA)  
Short-Circuit and Thermal-Overload Protection  
Available in Thermally Efficient, Space-Saving
