产品描述

The EV7740DN-00B is the evaluation board for the MP7740, a stereo 15W 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 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 efficiency. The circuit is based on the MPS’ AAMTM proprietary variable frequency topology that delivers excellent linearity, fast response time and operates on a single power supply.

产品特性

  • 15W Output at VDD = 24V into a 4Ω load
  • THD+N = 0.018% at 1W, 8Ω, 1KHz
  • 90% Efficiency at 15W and VDD=24V with 4Ω load
  • Low Noise (103μV Typical)
  • 9.5V to 36V Operation from a Single Supply

技术参数
