NS4168 I2S Audio Power Amplifier Module DIY Class D Audio Amplifier Board with Headphone Jack with Case

NS4168 I2S Audio Power Amplifier Module DIY Class D Audio Amplifier Board with Headphone Jack with Case Popis

NS4168 Highly Integrated Class D Audio Amplifier Chip: Features a filter-less Class D architecture; delivers a output of 2.5W (at 5V with a 4Ω load) with to 80% conversion efficiency.
Supports I2S digital audio processing and NCN (anti-distortion) functionality. Automatically detects and adapts to sampling rates across the full 8kHz-96kHz range; equipped with a programmable digital high-pass filter to suit various acoustic configurations.
Includes over-current, over-temperature, and under-voltage protection; safeguards the amplifier chip and prevents damage to connected headphones or speakers, making it suitable for long-term, continuous operation.
Dual-mode audio output (Headphones or Speakers): Supports both headphone monitoring and external speaker playback; allows for free selection between the two modes.
