Stereo Headphone Amplifier with BassMax,  
Volume Control, and Input Mux  
MAX729  
General Description  
Features  
DirectDrive Headphone Amplifier Eliminates  
The MAX9729 stereo DirectDrive™ headphone amplifi-  
er features bass boost, volume control, an input mux,  
Bulky DC-Blocking Capacitors

and an I C/SMBus™-compatible serial interface. This  
3:1 Input Multiplexer with Digital-Fade Circuitry  
Software-Enabled Bass Boost  
32-Step Integrated Volume Control  
Beep Input with Programmable Output Level  
Low Quiescent Current  
makes the MAX9729 ideal for portable audio applica-  
tions where space is at a premium and performance is  
essential. The MAX9729 operates from a single 1.8V to  
3.6V, and uses Maxim’s patented DirectDrive architec-  
ture, eliminating the need for large DC-blocking capaci-  
tors. The headphone amplifiers deliver 52mW into a  
32Ω load, feature low 0.03% THD+N, and high 90dB  
PSRR. Maxim’s industry-leading click-and-pop sup-  
pression circuitry reduces audible transients during  
power and shutdown cycles.

I C-Compatible 2-Wire Interface  
Short-Circuit Protection  
1.8V to 3.6V Single-Supply Operation  
Available in Space-Saving, Thermally Efficient  
The BassMax feature boosts the bass response of the  
amplifier, improving audio reproduction for low-end  
headphones. The integrated volume control features 32  
discrete volume levels along with a ramping function to  
ensure smooth transitions during shutdown cycles and  
input selection. The MAX9729’s eight programmable  
maximum gain settings allow for a wide range of input  
signal levels. A 3:1 multiplexer/mixer allows the selection  
and summation of multiple stereo input signal sources.  
The MAX9729 also includes a dedicated BEEP input  
with independent attenuation control. BassMax, volume  
control, gain settings, and input selection are controlled
