  • High output power capability 4Wx25W/4Ω out power @ 14.4V, 1kHz, 10% THD, 4x45W max power
  • 2Ω driving capability (64W max power)
  • Full I2C bus driving
    • Standby
    • Independent front/rear soft play/mute
  • I2C bus digital diagnostics (including DC and AC load detection)
  • High efficiency enable/disable
  • Flexible fault detection through integrated diagnostic
  • DC offset detection
  • Four independent short circuit protection
  • Clipping detector pin with selectable threshold (2%/10%)
  • Standby/mute pin
  • Linear thermal shutdown with multiple thermal warning
  • ESD protection
  • Very robust against misconnections
  • Improved SVR suppression during battery transients
  • Capable to operate down to 6V (e.g. "Start-stop")
