The MP7731 is a mono, 5W to 30W 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: • Start Up / Shut Down Pop Elimination • Short Circuit Protection Circuits• 180mΩ Power MOSFETs • Mute / Standby Mode The MP7731 utilizes a full bridge output structure capable of delivering 5W - 30W into 4Ω speakers. As in all other MPS Class D Audio Amplifiers, this device exhibits the high fidelity of a Class AB amplifier with an efficiency of 90%. The circuit is based on the MPS’ proprietary variable frequency topology Analog Adaptive Modulation (AAM, Patent No. 6,420,930; other patents pending) that delivers excellent PSRR, fast response time and operates on a single power supply.
