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: 180m? 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 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’ proprietary variable frequency topology that delivers low distortion, fast response time and operates on a single power supply.
