element14 Ships MERUS Class D Audio Amplifier Solutions from Infineon

element14 is shipping Infineon’s MERUS range of Class D audio amplifier solutions, which use pioneering multilevel switching technology to increase audio performance and reduce power loss during operation.

Infineon MERUSInfineon’s enhanced design and production standards deliver extreme reliability and stability for the entire product lifetime. The new range offers improved power efficiency, decreased size, weight, electromagnetic interference and lower overall cost than traditional solutions on the market.

Electronics engineers can utilize MERUS Class D audio solutions in a range of applications such as battery-operated speakers, wireless and docking speakers, soundbars, multiroom systems, and home theatre systems. The MERUS portfolio includes fully integrated monolithic audio amplifier ICs, multi-chip audio amplifier modules (MCMs), as well as discrete audio amplifier driver IC and power MOSFET solutions, scalable to meet the most stringent and demanding application needs.

The products now available from element14 include:

  • The MA12040P (for 4-18V supply voltage range) and the MA12070P (for 4-26V supply voltage range), suitable for battery-operated speakers, wireless and docking speakers, soundbars and multiroom/home theatre systems, both feature an embedded digital power management scheme with an algorithm that dynamically adjusts switching frequency and modulation to optimize power loss and EMI across the output power range. Integrated digital-to-analog converters enable digital I2S audio stream input. The amplifiers support sample rates from 44.1 kHz to 192 kHz and offer protection against DC, short circuits, over-temperature, and under-voltage situations. Flexible “power mode profiles” allow the user to utilize the multilevel switching technique for very low power loss or very high audio performance. Also available, for Analog input, are the complementary MA12040 and MA12070.
  • The EVAL_AUDIO_MA12070P easy to use audio evaluation kit contains all the elements needed to evaluate the highly power-efficient MERUS digital input multilevel class D amplifier 2×80W (MA12070P). The IC is specifically targeted for high-performance filter-less and heatsink-free audio applications and suitable for applications such as voice-controlled audio and professional audio where it is essential to maximize dynamic range and audio performance while minimizing power dissipation and power loss

Infineon’s MERUS range of Class D audio amplifier solutions are available from Farnell in EMEA, Newark in North America and element14 in APAC.
