2.6W Stereo Audio Power Amplifier and  
DirectDrive Headphone Amplifier  
General Description  
Features  
The MAX9779 combines a stereo, 2.6W audio power  
amplifier and stereo DirectDrive™ 110mW headphone  
amplifier in a single device. The headphone amplifier  
uses Maxim’s patented DirectDrive architecture that pro-  
duces a ground-referenced output from a single supply,  
eliminating the need for large DC-blocking capacitors,  
saving cost, space, and component height. A high 90dB  
PSRR and low 0.01% THD+N ensures clean, low-distor-  
tion amplification of the audio signal through the Class  
AB speaker amplifiers.  
No DC-Blocking Capacitors Required—Provides  
Industry’s Most Compact Notebook Audio  
Solution  
PC2001 Compliant  
5V Single-Supply Operation

110mW DirectDrive Headphone Amplifiers  
High 90dB PSRR  
The MAX9779 features a single-supply voltage, a shut-  
down mode, logic-selectable gain, and a headphone  
sense input. Industry-leading click-and-pop suppres-  
sion eliminates audible transients during power and  
shutdown cycles.  
Low-Power Shutdown Mode  
Industry-Leading Click-and-Pop Suppression  
Low 0.01% THD+N at 1kHz  
The MAX9779 is offered in a space-saving, thermally effi-  
cient 28-pin thin QFN (5mm x 5mm x 0.8mm) package.  
The device has thermal-overload and output short-circuit  
protection, and is specified over the extended -40°C to  
+85°C temperature range.
