performance.

Key Features

  • Output Power Po:2.5W(VDD=5V, RL=4Ω).
  • Operating Voltage:3.0V～5.5V.
  • 0.2%THD+N（VDD=5V, RL=4Ω, Po=1W）.
  • 80% efficiency (VDD=5V, RL=4Ω, Po=2.5W).
  • Default 12S serial digital audio input interface.
  • Supports wide range sampling rate: 8kHz~96kHz.
  • Left or right channel is available by setting the level of CTRL pin.
  • Output NCN function.
  • Filterless Class D amplifier.
  • Excellent “power on, power off” noise suppression.
  • Overcurrent protection, overhea.
