2.6W Stereo Audio Power Amplifiers and  
DirectDrive Headphone Amplifiers  
General Description  
Features  
The MAX9750/MAX9751/MAX9755 combine 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 produces 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-distortion amplification of the audio  
signal.  
No DC-Blocking Capacitors Required—Provides  
Industry’s Most Compact Notebook Audio  
Solution  
PC2001 Compliant  
5V Single-Supply Operation  
Class AB 2.6W Stereo BTL Speaker Amplifiers  
110mW DirectDrive Headphone Amplifiers  
High 90dB PSRR  
The MAX9750 features an analog volume control, and a  
BEEP input. The MAX9751 features a 2:1 input multiplexer,  
allowing multiple audio sources to be selected. All devices  
feature a single-supply voltage, a shutdown mode, logic-  
selectable gain, and a headphone sense input. Industry-  
leading click-and-pop suppression 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  
Short-Circuit and Thermal Protection  
Selectable Gain Settings  
The MAX9750/MAX9751/MAX9755 are offered in space-  
saving, thermally efficient 28-pin thin QFN (5mm x 5mm  
x 0.8mm) and 28-pin TSSOP-EP packages. Both devices  
have thermal-overload and output short-circuit protec-  
tion, and are specified over the extended -40°C to +85°C  
temperature range.
