Low-Cost, Mono/Stereo,  
1.4W Differential Audio Power Amplifiers  
8/MAX719  
General Description  
Features  
The MAX9718/MAX9719 differential input audio power  
amplifiers are ideal for portable audio devices with  
internal speakers. The differential input structure  
improves noise rejection and provides common-mode  
rejection. A bridge-tied load (BTL) architecture mini-  
mizes external component count, while providing high-  
quality, power audio amplification. The MAX9718 is a  
single-channel amplifier while the MAX9719 is a dual-  
channel amplifier for stereo systems. Both devices  
deliver 1.4W continuous average power per channel to  
a 4Ω load with less than 1% THD+N while operating  
from a single +5V supply. The devices are available as  
adjustable gain amplifiers or with internally fixed gains  
of 0dB, 3dB, and 6dB to reduce component count.  
o 2.7V to 5.5V Single-Supply Operation  
o Very High -93dB PSRR at 217Hz  
o 1.4W into 4Ω at 1% THD+N (per Channel)  
o Differential Input  
o Internal Fixed Gain to Reduce Component Count  
o Adjustable Gain Option (MAX9718A/H/MAX9719A)  
o 100nA Low-Power Shutdown Mode  
o No Audible Clicks or Pops at Power-Up/Down  
o Improved Performance Pin-Compatible Upgrade  
to LM4895 (MAX9718D/G)  
o 1.8V Logic Compatible  
A shutdown input disables the bias generator and  
amplifiers and reduces quiescent current consumption  
to less than 100nA. The MAX9718 shutdown input can  
be set as active high or active low. These devices fea-  
ture Maxim’s comprehensive click-and-pop suppres-  
sion circuitry that reduces audible clicks and pops  
during startup and shutdown.
