Product Description

The EV7747DQ-00A is the evaluation board for the MP7747, a 20W 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 MP7747 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’ AAMTM proprietary variable frequency topology that delivers excellent linearity, fast response time and operates on a single power supply.

Product Features

  • 2 x 20W Output at VDD = 24V into a 4Ω load
  • THD+N = 0.02% at 1W, 8Ω, 1kHz
  • 91% Efficiency at 20W and VDD=24V with 4Ω load
  • Low Noise (103μV Typical)
  • 9.5V to 36V Operation from a Single Supply

20W Class-D Mono Single Ended Audio Amplifier

The MP7747 is a mono 20W 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, Start-up/shut-down,pop elimination, Short circuit protection circuits. The MP7747 utilizes a single ended output structure capable of delivering 20W into 4O 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. The MP7747 features programmable VDD shutdown voltage by controlling the UVP node voltage. The default VDD UVP voltage (rising threshold) is 8.4V if the UVP pin is NC.
