3. MP7722DF
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:
180mΩ 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 4Ωspeakers.
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.
