MAX98304 Evaluation Kit
General Description
Features
S Filterless Operation Passes Radiated Emissions
The MAX98304 evaluation kit (EV kit) is a fully assembled
and tested circuit board that uses the MAX98304 filterless
Class D amplifier to drive a speaker in portable audio
applications. The EV kit comes with a MAX98304EWL+
in a 9-bump, 0.3mm pitch wafer-level package (WLP).
Designed to operate from a 2.5V to 5.5V DC power
supply, the EV kit is capable of delivering 3.2W into a
4I load. The EV kit accepts differential or single-ended
input signals.
