2x80W ultra power efficient, fully integrated audio amplifier IC with analog input
MA12070 is a highly efficient, fully integrated, digital audio power amplifier IC, based on multi-level switching technology. It supports a 4-26V supply voltage range, allowing it to be used in many different audio applications.
Summary of Features
Multi-level switching technology with 3-level and 5-level modulation
2×80W peak output power (26V PVDD, RL = 4Ω, 10% THD+N level)
Supply voltages: +4V to +26V (PVDD) and +5V (A/DVDD)
Suitable for 2.0, 2.1, 4.0, 1.0 output stage configurations
4th order feedback error control
<160mW Idle power dissipation (26V PVDD, all channels switching)
>80% efficiency at 2W power (1kHz sine, 8Ω)
>91% efficiency at full Power (1kHz sine, 8Ω)
Audio performance (PMP2): >110dB SNR (A-w, rel. to 1% THD+N power level)
45µV output integrated noise (A-w)
0.004% THD+N at high output levels
I2C control (four selectable addresses)
Built-in protection: under-voltage-lockou
t, over-temperature warning/error, short-circuit/overlo
ad protection, power stage pin-to-pin short-circuit, error-reporting through serial interface (I2C), DC protection
Benefits
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
Potential Applications
Portable audio - battery operated speakers, on-the-go bluetooth speakers, docking speakers, boom boxes, wearable speakers
Home audio – multi-room systems, television, soundbars, home theater systems, stand-alone components
Voice controlled audio
Pro audio - active monitor speakers, power-over-ethernet (PoE), multi-channel systems
Applications
Automotive telematics control unit (TCU)
Smart speaker designs
