Product Description

The EV7720DS-00A 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: 180m? power MOSFETs Startup / Shutdown pop elimination Short circuit protection circuits Mute / Standby

The MP7720 utilizes a single ended output structure with capacitor divider configuration capable of delivering 20W into 4? 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 4? load
