Product Summary

The MP7782DF is a mono, 50W Class D Audio Amplifier. It is one of MPS’ second generation fully integrated audio amplifiers which dramatically reduces solution size by integrating four 180mΩ power MOSFETs in a space saving TSSOP20 package. The MP7782DF utilizes a full bridge output structure capable of delivering 50W into 6Ω speakers. The applications of the MP7782DF include MP3 Systems, Surround Sound Systems, Multimedia Computers, Televisions, Home Stereos, DVD and VCD Players, Game Devices and Systems, Subwoofers.
