Product Features:

  • This mini amplifier board is a stereo class D audio power amplifier
  • Can be provided in class D amplifier efficiency performance of the class AB amplifier. Structure of class D
  • Able to provide 3 w power efficiency at more than 85%.
  • New type of structure without filter can eliminate the traditional class D amplifier output low-pass filter
  • NOTE:Positive and negative power supply can not be reversed, the power supply voltage can not exceed 5.5V, these two violations could result in IC damage
  • NOTE:with high gain buffer, not any component parameter changes on a board, does not conform to the parameters will lead to damage of the IC.
  • NOTE:please use audio input line belt shielding line, power input
