Product Details

The MAX98355 evaluation kit (EV kit) is a fully assembled and tested PCB that evaluates the MAX98355 PCM digital input Class D power amplifier. The EV kit operates from a single 2.5V to 5.5V DC power supply and is capable of delivering 3.2W into a 4Ω load. The device outputs can be connected directly to a speaker load for filterless applications. However, a filter can be added to ease evaluation. The MAX98355A accepts standard I²S data and the MAX98355B accepts left-justified digital audio data. Both ICs support time-division multiplexed (TDM) data.
