Infineon stock last updated:
This product is not for a new design. Check out our new MERUS™ multilevel gen2 class D amplifiers MA2304DNS and MA2304PNS .MA12040P is a highly efficient, fully integrated audio power amplifier IC, based on multi-level switching technology. It supports a 4-18V supply voltage range, allowing it to be used in many different audio applications.

特長

  • Multi-level switching technology with 3-level and 5-level modulation
  • 2×40W peak output power (18V PVDD, RL = 4Ω, 10% THD+N level)
  • Supply voltages: +4V to +18V (PVDD) and +5V (A/DVDD)
  • Suitable for 2.0, 2.1, 4.0, 1.0 output stage configurations
  • 4th order feedback error control
  • <110mW Idle power dissipation (18V PVDD, all channels switching)
  • >77% efficiency at 1W power (1kHz sine, 8Ω)
  • >92% efficiency at full power (1kHz sine, 8Ω)
  • Audio performance (PMP2): >98dB DNR (A-w, rel. to 1% THD+N power level)
  • 135µV output integrated noise (A-w)
  • 0.006% THD+N at high output levels
  • I2C control (four selectable addresses)
  • Built-in volume control and limiter
  • Built-in protection: under-voltage-lockout, over-temperature warning/error, short-circuit/overload protection, power stage pin-to-pin short-circuit, error-reporting through serial interface (I2C), DC protection

利点

  • Unparalleled power efficiency - optimized for music playback with very low power losses and cool operation
  • Ultra compact, fully integrated solution – high power output in a small form factor
  • HD audio quality & best in class audio performance - high dynamic range, low distortion, low noise
  • Low interference / EMI emission - EMC compliance without use of large filter component
  • High suppression of supply ripples
  • Reduced BoM and associated system cost savings
  • Reduction of battery sizes through better power efficiency
  • Eliminates complex dynamic rail tracking
  • Offers filter-less amplification and eliminates LC filters in many applications
  • Heatsink free operation with EPAD-down package
  • Flexible solution – highly configurable for tailored performance in individual applications
