Product Description

The MP7722 is a stereo 2 x 20W Class-D Audio Amplifier. It is one of MPS? second generation fully integrated audio amplifiers which dramatically reduces solution size by integrating the following: ?180mO power MOSFETs ?Startup / Shutdown pop elimination ?Short circuit protection Mute / Standby The MP7722 utilizes a single ended output structure capable of delivering 2 x 20W into 4O 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? proprietary variable frequency topology that delivers low distortion, fast response time and operates on a single power supply.

Kit details

The EV7722DF-00C 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: • 180m? power MOSFETs • Startup / Shutdown pop elimination • Short circuit protection circuits • Mute / Standby

The MP7722 utilizes a single ended output structure capable of delivering 2x20W 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 linearity, fast response time and operates on a single power supply.
