Product Details

The MAX98356 evaluation kit (EV kit) is a fully assembled and tested PCB that evaluates the MAX98356 PDM 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.

Applications

  • Cellular Phones
  • Notebook Computers
  • Portable Media Players
  • Tablets
  • Ultrasonic Devices
