Product Details

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 4Ω 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.
