MAX98400A Evaluation Kit  
General Description  
Features  
S 8V to 28V Single DC Power-Supply Operation  
The MAX98400A evaluation kit (EV kit) configures the  
MAX98400A Class D amplifier to drive 2x20W into a pair of  
8I speakers in stereo mode, or 1x40W into a 4I speaker  
in mono mode, for audio applications. The EV kit operates  
from an 8V to 28V DC power supply. The EV kit is config-  
ured for +20.1dB gain. The EV kit accepts a pair of single-  
ended or differential input signals and provides two sets of  
differential outputs for speakers.  
S Fully Differential Inputs and Outputs  
S Drives 2x20W into 8I Speakers in Stereo Mode  
S Drives 1x40W into 4I Speaker in Mono Mode  
S Limiter Control  
S Thermal Foldback  
S Shutdown Control  
The EV kit has two independent MAX98400A circuits,  
demonstrating direct speaker driving (for low component  
count) and filtered output driving (for ease of evaluation).  
The EV kit comes with two MAX98400AETX+ devices  
installed.  
S Evaluates the MAX98400A in a 36-Pin TQFN  
Package with an Exposed Pad  
S U1 Configured for Filterless Output  
S U2 Configured for Filtered Output  
S Fully Assembled and Tested  
The EV kit provides an option to control the limiter,  
thermal foldback, input configuration, gain, shutdown,  
and mono mode of the MAX98400A. The EV kit also  
provides an input pad to accept an optional external power  
supply for powering the device’s preamplifiers. The EV kit  
includes convenient audio input and output connectors.
