Specifications of MAX98300EVKIT+TDFN

Lead Free Status / RoHS Status
Lead free / RoHS Compliant
19-5461; Rev 0; 7/10
The MAX98300 evaluation kit (EV kit) is a fully
assembled and tested circuit board that uses the
MAX98300 filterless Class D amplifier to drive a speak-
er in portable audio applications. The EV kit comes
with a MAX98300 IC in an 8-pin TDFN package.
Designed to operate from a 2.6V to 5.5V DC power
supply, the EV kit is capable of delivering 2.6W into a
4I load. The EV kit accepts differential or single-ended
input signals.
