EVALUATION KIT  
AVAILABLE  
1.2W, Low-EMI, Filterless, Mono Class D Amplifier  
with Stereo DirectDrive Headphone Amplifiers  
MAX970  
General Description  
Features  
1.2W Filterless Class D Amplifiers Pass FCC  
The MAX9770 combines a mono, filterless, Class D  
speaker amplifier and stereo DirectDrive® headphone  
amplifier in a single device. The MAX9770 operates  
from a single 2.5V to 5.5V supply and includes features  
that reduce external component count, system cost,  
board space, and offer improved audio reproduction.  
Class B Radiated EMI Standards with 100mm  
of Cable  
Spread-Spectrum Mode Offers 5dB EMI  
Improvement over Conventional Methods  
80mW DirectDrive Headphone Amplifier  
Eliminates Bulky DC-Blocking Capacitors  
High 85dB PSRR at 217Hz  
The speaker amplifier makes use of Maxim’s Class D  
architecture, providing Class AB performance with Class  
D efficiency, conserving board space, and extending  
battery life. The speaker amplifier delivers 1.2W into an  
8Ω load while offering efficiencies above 85%. A spread-  
spectrum modulation scheme reduces radiated emis-  
sions caused by the modulation frequency. Furthermore,  
the MAX9770 oscillator can be synchronized to an exter-  
nal clock through the SYNC input, avoiding possible  
problem frequencies inside a system. The speaker  
amplifier features THD+N as low as 0.025%, high 70dB  
PSRR, and SNR in excess of 90dB.  
85% Efficiency  
Low 0.015% THD+N  
Industry-Leading Click-and-Pop Suppression  
Integrated 3-Way Input Mixer/Multiplexer  
(MAX9770)  
Logic-Adjustable Gain  
Short-Circuit and Thermal Protection  
Available in Space-Saving, Thermally Efficient  
Packages  
The headphone amplifiers feature Maxim’s DirectDrive  
architecture that produces a ground-referenced output  
from a single supply, eliminating the need for large DC-  
blocking capacitors. The headphone amplifiers deliver up  
to 80mW into a 16Ω load, feature low 0.015% THD+N,  
high 85dB PSRR, and 8kV ESD-protected outputs. A  
headphone sense input detects the presence of a head-  
phone, and automatically configures the amplifiers for  
either speaker or headphone mode.

The MAX9770 includes internally set, logic-selectable  
gain, and a comprehensive input multiplexer/mixer, allow-  
ing multiple audio sources to be selected and for true  
mono reproduction of a stereo source in speaker mode.  
Industry-leading click-and-pop suppression eliminates  
audible transients during power and shutdown cycles. A  
low-power shutdown mode decreases supply current  
consumption to 0.1µA, further extending battery life.
