MAX98303 Evaluation Kit
General Description
The MAX98303 evaluation kit (EV kit) is a fully assembled
and tested PCB that evaluates the MAX98303 stereo
3.1W Class D amplifier in a 16-bump, 0.4mm pitch
wafer-level package (WLP). The EV kit operates from
a single 2.6V to 5.5V DC power supply and is capable
of delivering 3.1W into a 4I load. The EV kit accepts
a differential or single-ended audio input and provides
differential outputs for the speaker. The device outputs
can be connected directly to a speaker load for filterless
applications; however, a filter can be added to ease
evaluation.
