2 x 1.5W, Stereo Class D Audio Subsystem  
with DirectDrive Headphone Amplifier  
5/MAX976  
General Description  
Features  
Unique Spread-Spectrum Modulation and Active  
The MAX9775/MAX9776 combine a high-efficiency  
Class D, stereo/mono audio power amplifier with a  
mono DirectDrive® receiver amplifier and a stereo  
DirectDrive headphone amplifier.  
Emissions Limiting Significantly Reduces EMI  
3D Stereo Enhancement (MAX9775 Only)  
Up to 3 Stereo Inputs  
Maxim’s 3rd-generation, ultra-low-EMI, Class D audio  
power amplifiers provide Class AB performance with  
Class D efficiency. The MAX9775/MAX9776 deliver  
1.5W per channel into a 4Ω load from a 5V supply and  
offer efficiencies up to 79%. Active emissions limiting  
circuitry and spread-spectrum modulation greatly  
reduce EMI, eliminating the need for output filtering  
found in traditional Class D devices.  
1.5W Stereo Speaker Output (4Ω, V  
= 5V)

50mW Mono Receiver/Stereo Headphone Outputs  
(32Ω, V = 3.3V)

470mW)  
I2C Control—Input Configuration, Volume Control,  
Output Mode  
The MAX9775/MAX9776 utilize a fully differential archi-  
tecture, a full-bridged output, and comprehensive click-  
and-pop suppression. A 3D stereo enhancement  
function allows the MAX9775 to widen the stereo sound  
field immersing the listener in a cleaner, richer sound  
experience than typically found in portable applications.  
The devices utilize a flexible, user-defined mixer archi-  
tecture that includes an input mixer, volume control, and  
output mixer. All control is done through I2C.  
Click-and-Pop Suppression  
Low Total Harmonic Distortion (0.03% at 1kHz)  
Current-Limit and Thermal Protection  
Available in Space-Saving, 36-Bump WLP (3mm x  
3mm) and 32-Pin TQFN (5mm x 5mm) Packages  
Ordering Information  
CLASS D  
AMPLIFIER  
PART  
PIN-PACKAGE  
The mono receiver amplifier and stereo headphone  
amplifier use Maxim’s 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.

The MAX9775 is available in a 36-bump WLP (3mm x  
3mm) package. The MAX9776 is available in a 32-pin  
TQFN (5mm x 5mm) or a 36-bump WLP (3mm x 3mm)  
package. Both devices are specified over the extended  
-40°C to +85°C temperature range.  
Applications  
Cell Phones
