The EV7748S-F-00A is the 2.1 channels configuration evaluation board for the MP7748S, a 30W Single-ended or 60W Mono 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 MP7748S utilizes Single-ended structure Bridge Tied Load output structure capable of delivering 60W into 8Ω 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.


  • 30W Stereo Single-ended Output at VDD = 30V into 4Ω loads
  • 60W BTL Output at VDD = 30V into a 8Ω load
  • THD+N = 0.02% at 1W, 8Ω, 1kHz, SE and BTL, VDD = 24V
  • 93% Efficiency at 40W and VDD=24V with 8Ω load, BTL;  2 x 10W and VDD = 24V with 8Ω load, Single-ended
  • Low Noise (150μV Typical)
  • 9.5V to 36V Operation from a Single Supply
