Stereo, High-Power, Class D Amplifiers  
General Description  
Features  
S Wide 8V to 28V Supply Voltage Range  
The MAX98400A/MAX98400B Class D amplifiers provide  
high-performance, thermally efficient amplifier solutions. The  
MAX98400A delivers 2x20W into 8Iloads or 1x40W into a  
4Iload. The MAX98400B delivers 2x12W into 8Iloads.  
S Single-Supply Operation  
S Low EMI: Active Emissions Limiting  
S Clipping Limiter  
An integrated limiting circuit prevents output clipping  
distortion, protects small speakers from transient volt-  
ages, and reduces power dissipation.  
S Low Quiescent Current  
S Thermal Foldback  
A thermal-foldback feature can be enabled to automati-  
cally reduce the output power at above a junction tem-  
perature of +120NC. Traditional thermal protection is also  
available in addition to robust overcurrent protection.  
S Thermal and Overcurrent Protection  
Applications  
LCD/PDP Televisions  
LCD Monitors  
The ICs operate from a single 8V to 28V supply and  
provide a high 67dB PSRR, eliminating the need for a  
regulated power supply. They offer up to 90% efficiency  
from a 12V supply.  
MP3 Docking Stations  
Notebook PCs  
Filterless modulation allows the ICs to pass EN55022B  
EMI limits with 1m cables using only a low-cost ferrite  
bead and small-value capacitor on each output.
