产品描述

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: • 250mΩ power MOSFETs • Startup / Shutdown pop elimination • Short circuit protection circuits The MP7740 utilizes a single ended output structure capable of delivering 15W into 4Ω 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.
