19-3678; Rev 0; 7/05  
20W/40W, Filterless, Spread-Spectrum,  
Mono/Stereo, Class D Amplifier  
General Description  
Features  
The MAX9708 mono/stereo, Class D audio power ampli-  
fier delivers up to 2 x 21W into an 8Ω stereo mode and  
1 x 42W into a 4Ω load in mono mode while offering up  
to 87% efficiency. The MAX9708 provides Class AB  
amplifier performance with the benefits of Class D effi-  
ciency, eliminating the need for a bulky heatsink and  
conserving power. The MAX9708 operates from a single  
+10V to +18V supply, driving the load in a BTL configu-  
ration.  
♦ 2 x 21W Output Power in Stereo Mode  
(8Ω, THD = 10%)  
♦ 1 x 42W Output Power in Mono Mode  
(4Ω, THD = 10%)  
♦ High Efficiency: Up to 87%  
♦ Filterless Class D Amplifier  
♦ Unique Patented Spread-Spectrum Mode  
♦ Programmable Gain (+22dB, +25dB, +29.5dB,  
+36dB)  
The MAX9708 offers two modulation schemes: a fixed-  
frequency modulation (FFM) mode, and a spread-spec-  
trum modulation (SSM) mode that reduces  
EMI-radiated emissions. The MAX9708 can be synchro-  
nized to an external clock from 600kHz to 1.2MHz. A  
synchronized output allows multiple units to be cascad-  
ed in the system.  
♦ High PSRR (90dB at 1kHz)  
♦ Differential Inputs Suppress Common-Mode  
Noise  
♦ Shutdown and Mute Control  
♦ Integrated Click-and-Pop Suppression  
♦ Low 0.1% THD+N  
♦ Current Limit and Thermal Protection  
♦ Programmable Thermal Flag  
♦ SYNC Input/Output  
Features include fully differential inputs, comprehensive  
click-and-pop suppression, and four selectable-gain set-  
tings (22dB, 25dB, 29.5dB, and 36dB). A pin-program-  
mable thermal flag provides seven different thermal  
warning thresholds. Short-circuit and thermal-overload  
protection prevent the device from being damaged  
during a fault condition.  
♦ Available in Thermally Efficient, Space-Saving  
Packages: 56-Pin TQFN and 64-Pin TQFP  
The MAX9708 is available in 56-pin TQFN (8mm x 8mm  
x 0.8mm) and 64-pin TQFP (10mm x 10mm x 1.4mm)  
packages, and is specified over the extended  
-40°C to +85°C temperature range.
