The NAU83P20 is single supply, 20W, high efficiency, Class-D audio power stage for driving Stereo bridge-tied speakers. Operating from a single VDD 8V-24V supply, the design includes under-voltage, over-current and over-temperature detection.


  • Class D power 2x20W into 8Ohms (10% THD)
  • Typical power efficiency of 90%
  • 105dB SNR
  • Slew control
  • 3V LDO to power PWM controller
  • Supports multiple output configurations:
    - 2-CH Bridged outputs (20Wx2)
    - 4-CH single ended outputs (10Wx4)
    - 2-CH single ended + 1-CH bridged (10Wx2 + 20Wx1)
  • Fault Detection:
    - Over-Temperature
    - Under-Voltage
    - Over-Current
