2 x 1.5W, Stereo Class D Audio Subsystem  
with DirectDrive Headphone Amplifier  
5/MAX976  
General Description  
Features  
o 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  
o 3D Stereo Enhancement (MAX9775 Only)  
o 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.  
o 1.5W Stereo Speaker Output (4Ω, V  
= 5V)  
DD  
o 50mW Mono Receiver/Stereo Headphone Outputs  
(32Ω, V = 3.3V)  
DD  
o High PSRR (68dB at 217Hz)  
o 79% Efficiency (V  
= 3.3V, R = 8Ω, P  
=
OUT  
DD  
L
470mW)  
o 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.  
o Click-and-Pop Suppression  
o Low Total Harmonic Distortion (0.03% at 1kHz)  
o Current-Limit and Thermal Protection

PART  
The mono receiver amplifier and stereo headphone  
amplifier use 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.
