Windows Vista-Compliant Class D Speaker  
Amplifiers with DirectDrive Headphone Amplifiers  
1/MAX792  
General Description  
Features  
The MAX9791 combines a stereo 2W Class D power  
amplifier, a stereo 180mW DirectDrive® headphone  
amplifier, and a 120mA low-dropout (LDO) linear regu-  
lator in a single device. The MAX9792 combines a  
mono 3W Class D power amplifier, a stereo 180mW  
DirectDrive headphone amplifier, and a 120mA LDO  
linear regulator in a single device.  
o Windows Vista® Premium Compliant  
o Low EMI Filterless Class D Speaker Amplifiers  
Pass EN55022B Emissions Limit with 30cm of  
Speaker Cable  
o 180mW DirectDrive Headphone Amplifier  
o Excellent RF Immunity  
o Integrated 120mA LDO  
o Eliminates Headphone Ground Loop Noise  
o Wake-on-Beep Function  
o Click-and-Pop Suppression  
o Short-Circuit and Thermal-Overload Protection  
The MAX9791/MAX9792 feature Maxim’s DirectDrive  
headphone amplifier architecture that produces a  
ground-referenced output from a single supply, eliminat-  
ing the need for large DC-blocking capacitors, saving  
cost, board space, and component height. High 107dB  
DC PSRR and low 0.006% THD+N ensure clean, low-  
distortion amplification of the audio signal.  
The ground sense feature senses and corrects for the  
voltage difference between the output jack ground and  
device signal ground. This feature minimizes head-  
phone amplifier crosstalk by sensing the impedance in  
the ground return trace and correcting for it at the out-  
put jack. This feature also minimizes ground-loop noise  
when the output socket is used as a line out connection  
to other grounded equipment (for example, a PC con-  
nected to a home hi-fi system).  
The MAX9791/MAX9792 feature low RF susceptibility,  
allowing the amplifiers to successfully operate in close  
proximity to wireless applications. The MAX9791/  
MAX9792 Class D amplifiers feature Maxim’s spread-  
spectrum modulation and active emissions limiting cir-  
cuitry. Industry-leading click-and-pop suppression  
eliminates audible transients during power-up and shut-  
down cycles.

The MAX9791/MAX9792 wake-on-beep feature wakes  
up the speaker and headphone amplifiers when a qual-  
ified beep signal is detected at the BEEP input.  
For maximum flexibility, separate speaker and head-  
phone amplifier control inputs provide independent  
shutdown of the speaker and headphone amplifiers.  
Additionally the LDO can be enabled independently of  
the audio amplifiers.
