Product Description

The EV7742DF-00D is the evaluation board for the MP7742, a stereo 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 MP7742 utilizes a single ended output structure capable of delivering 2x15W 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.

Product Features

  • 15W Output at VDD = 24V into a 4Ω load
  • THD+N = 0.04% at 1W, 8Ω, 1kHz
  • 90% Efficiency at 15W and VDD=24V with 4Ω load
  • Low Noise (103μV Typical)
  • 9.5V to 28V Operation from a Single Supply
