The EV7748DF-00A is the evaluation board for the MP7748, a 2 x 20W stereo Class D Audio Amplifier. It is one of MPS’ products of fully integrated audio amplifiers which dramatically reduce solution size by integrating the following:

• 250mΩ power MOSFETs
• Startup / Shutdown pop elimination
• Short circuit protection circuits

The MP7748 utilizes a single ended output structure capable of delivering 20W into 4Ω speakers. MPS Class D Audio Amplifiers exhibit the high fidelity of a Class A/B amplifier at high efficiency. The circuit is based on the MPS’ AAM^TM proprietary variable frequency topology that delivers excellent linearity, fast response time and operates on a single power supply.
