Product Description

The EV7722DF-02A is the evaluation board for the MP7722. The MP7722 is a stereo 20W Class D Audio Amplifier. It is one of MPS’ second generation of fully integrated audio amplifiers which dramatically reduces solution size by integrating the following:

  • 180mΩ power MOSFETs
  • Startup / Shutdown pop elimination
  • Short circuit protection circuits
  • Mute / Standby

The MP7722 utilizes a single ended output structure with capacitor divider configuration capable of delivering 2x20W into 4Ω speakers. MPS Class D Audio Amplifiers exhibit the high fidelity of a Class A/B amplifier at efficiencies greater than 90%. The circuit is based on the MPS’ AAMTM proprietary variable frequency topology that delivers excellent linearity, fast response time and operates on a single power supply.

Product Features

  • 20W Output at VDD = 24V into a 4Ω load
  • THD+N = 0.08% at 1W, 8Ω
  • 90% Efficiency at 20W
  • 9.5V to 24V Operation from a Single Supply
  • Mute/Standby Modes (Sleep)
