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.
