12W+12W, Low-EMI, Spread-Spectrum,  
Stereo, Class D Amplifier  
General Description  
Features  
The MAX9741 stereo Class D audio power amplifier  
provides Class AB amplifier performance with Class D  
efficiency, conserving board space and eliminating the  
need for a bulky heatsink. Using a high-efficiency Class  
D architecture, it delivers 12W continuous output power  
into 8loads. Proprietary modulation and switching  
schemes render the traditional Class D EMI suppression  
output filter unnecessary.  
Low-EMI Class D Amplifier  
Spread-Spectrum Mode Reduces EMI  
Passes FCC EMI Limits with Ferrite Bead Filters  
with 0.5m Cables  
12W+12W Continuous Output Power into 8Ω  
Low 0.1% THD+N  
The MAX9741 offers two modulation schemes: a fixed-fre-  
quency mode (FFM), and a spread-spectrum mode (SSM)  
that reduces EMI-radiated emissions. The device utilizes a  
fully differential architecture, a full bridged output, and  
offers comprehensive click-and-pop suppression.  
High PSRR (80dB at 1kHz)  
10V to 25V Single-Supply Operation  
Differential Inputs Minimize Common-Mode Noise  
Pin-Selectable Gain Reduces Component Count  
Industry-Leading Click-and-Pop Suppression  
Short-Circuit and Thermal-Overload Protection  
The MAX9741 features high 80dB PSRR, low 0.1%  
THD+N, and SNR in excess of 100dB. Short-circuit and  
thermal-overload protection prevent the device from  
being damaged during a fault condition. The MAX9741  
is available in a 56-pin TQFN (8mm x 8mm x 0.8mm)  
package. The MAX9741 is specified over the extended  
-40°C to +85°C temperature range.
