1.8W, Filterless, Stereo, Class D Audio Power  
Amplifier and DirectDrive Stereo Headphone Amplifier  
General Description  
Features  
Spread-Spectrum Modulation Reduces EMI  
The MAX9702 combines a highly efficient Class D  
speaker amplifier with a high-linearity Class AB head-  
phone amplifier. This ensures maximum battery life in  
speaker mode and maximum performance in head-  
phone mode. The MAX9702 delivers up to 1.1W per  
channel into an 8Ω load and 1.8W into a 4Ω load from a  
5V power supply. Maxim’s 2nd-generation, spread-  
spectrum modulation scheme renders the traditional  
Class D output filter unnecessary.

The MAX9702 speaker amplifier offers two modulation  
schemes: a fixed-frequency (FFM) mode and a spread-  
spectrum (SSM) mode that reduces EMI-radiated emis-  
sions. The MAX9702 speaker amplifier features a fully  
differential architecture, full-bridged (BTL) output, and  
comprehensive click-and-pop suppression. The  
MAX9702 speaker amplifier features high 75dB PSRR,  
low 0.07% THD+N, and SNR in excess of 97dB. Short-  
circuit and thermal-overload protection prevent the  
device from being damaged during a fault condition.  
High 73dB PSRR (f = 217Hz)  
I2C Programmable Gain Up to +21dB  
Integrated Click-and-Pop Suppression  
Low-Power Shutdown Mode (0.1µA)  
Short-Circuit and Thermal-Overload Protection  
8kV (HBM) ESD-Protected Headphone Driver  
Outputs  
Ordering Information  
The headphone amplifier uses Maxim’s DirectDriveTM  
architecture that produces a ground-referenced output  
from a single supply, eliminating the need for large DC-  
blocking capacitors, saving cost, board space, and  
component height. A high 80dB PSRR and low 0.02%  
THD+N ensures clean, low-distortion amplification of  
the audio signal.
