Product Description

The MP7721 is a stereo 2 x 10W Class D Audio Amplifier. It is one of MPS?second generation fully integrated audio amplifiers which dramatically reduces solution size by integrating the following: 250m? power MOSFETs Startup / Shutdown pop elimination Short circuit protection Mute / Standby The MP7721 utilizes a single ended output structure capable of delivering 2 x 10W into 8? 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 EV7721DF-00A is the evaluation board for the MP7721, a stereo 10W Class D Audio Amplifier. It is one of MPS’ productions of fully integrated audio amplifiers which dramatically reduces solution size by integrating the following: • 250m? power MOSFETs • Startup / Shutdown pop elimination • Short circuit protection circuits • Mute / Standby

The MP7721 utilizes a single ended output structure capable of delivering 2x10W into 8? 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.
