Product Description

The EV7751-F-00A is the evaluation board for the MP7751, a 20W stereo BTL Fix Freuquency Class D Audio Amplifier. It is one of MPS’ products of fully integrated audio amplifiers which dramatically reduce solution size by integrating the following:

  • 240mΩ power MOSFETs
  • Startup / Shutdown pop elimination
  • Short circuit protection circuits
  • Advanced EMI performance

The MP7751 utilizes Bridge Tied Load output structure capable of delivering stereo 20W into 8Ω speakers. It features in automatic shutdown function which can save power in battery-used system. The PLIMIT function is useful for limiting total output power by simply adjust a DC reference voltage at PLIMIT pin. MPS Class D Audio Amplifiers exhibit the high fidelity of a Class A/B amplifier at high efficiency.

Product Features

  • 20W Stereo BTL Output at VDD = 18V into 8Ω loads
  • 9.5W Stereo BTL Output at VDD = 12V into  8Ω loads
  • Better than 90% Efficiency at 9.5W x 2 and VDD=12V with 8Ω load, Stereo
  • Low Noise (120μV Typical)
  • 5V to 26V Operation from a Single Supply

Parametrics


5V to 26VDD, 2x 20W, Fixed-Frequency Stereo BTL Class-D Audio Amplifier

The MP7751 is an analog input, Class-D audio amplifier that can drive stereo speakers in a bridge-tied-load configuration. It is one of MPS’s suite of fully integrated audio amplifiers, which dramatically reduce solution size by integrating the following:

  • 240mΩ power MOSFETs
  • Start-up / Shutdown pop elimination
  • Short-circuit protection circuits
  • Advanced EMI performance

The MP7751 utilizes a stereo BTL structure capable of delivering 20W per channel into 8Ω speakers at an 18V power supply. MPS's Class-D audio amplifiers exhibit the high fidelity of a Class-AB amplifier at high efficiencies.

The MP7751 includes an internal circuit that allows the system to automatically shut down when no audio signal is detected. This feature is ideal for energy-saving products and battery-operated applications. 

It also has an adjustable power limit function. The PLIMIT circuit sets a limit on the output peak-to-peak voltage. This is accomplished by limiting the duty cycle to a fixed maximum value. This limit can be thought of as a virtual voltage rail, which is lower than the supply connected to PVCC. The MP7751 is available in a TSSOP-28EP package.
