Product Description

The EV0030 is the evaluation board for the MP7720, a mono 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 MP7720 utilizes a single ended output structure capable of delivering 20W 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 PSRR, fast response time and operates on a single power supply.

Product Features

  • 20W Output at VDD = 24V into a 4Ω load
  • THD+N = 0.04% at 1W, 8Ω
  • 93% Efficiency at 20W
  • Low Noise (190μV Typical)
  • Switching Frequency Up to 1MHz
  • 9.5V to 24V Operation from a Single Supply
  • Integrated Startup and Shutdown Pop Elimination Circuit
  • Thermal Protection
  • Integrated 180mΩ Switches
  • Mute/Standby Modes (Sleep)
  • Available in Tiny 8-Pin SOIC and PDIP Packages
