The MP7740 is a mono 15W Class D Audio Amplifier. It is one of MPS’ products 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 The MP7740 utilizes a single ended output structure capable of delivering 15W into 4? speakers. MPS Class D Audio Amplifiers exhibit the high fidelity of a Class A/B amplifier at high efficiencies. The circuit is based on the MPS’ proprietary variable frequency topology that delivers excellent linearity, fast response time and operates on a single power supply.
15W Output at VDD = 24V into a 4? load THD+N = 0.05% at 1W, 8? 90% Efficiency at 15W & VDD=24V Low Noise (103µV Typical) Switching Frequency Up to 1MHz 9.5V to 36V Operation from a Single Supply Integrated Startup and Shutdown Pop Elimination Circuit Thermal and Short Circuit Protection Integrated Power FETs Pin Compatible with MP7720 Available in Tiny 8-Pin SOIC Package
