The Power of Not Wasting Power

eximo® amplifiers cut power losses during operation, leading to several advantages in audio product design.

 

Battery Life and Battery Size

Power losses in the audio amplifier significantly affect battery lifetime in portable audio products. By cutting power losses, eximo™ amplifiers allow audio product designers to either extend battery lifetime or reduce the size of the costly Li-Ion battery.


Heatsinking

eximo® amplifiers enable greatly reduced heatsinking as the heat dissipation during typical operation is significantly reduced. In fact, in most cases the amplifier circuit board will offer sufficient heatsinking capability, even in relatively high-powered applications where other amplifiers would require a dedicated heatsink.


Lower Operating Temperatures

The low heat dissipation of eximo® amplifiers lead to a generally cooler operation inside the audio application. This gives a much larger headroom for periods of higher output power, for example during music playback at high volume levels.

Cooler operation also impacts the reliability of the audio application, due to a reduction of thermally accelerated aging of many system components.


A Green Technology

eximo® is a highly efficient technology, offering a significant reduction in energy consumption throughout the lifetime of a consumer audio product. Implementing eximo® technology in audio and audio/video applications supports consumer electronics manufacturers in complying with new legislative requirements as well as internal eco-friendly policies.
 

Less Filtering is More Freedom

Conventional class-D amplifiers typically require an L-C output filter to reconstruct the audio waveform before the amplified audio signal reaches the speaker*. The filter accounts for a large portion of the size and area for the total amplifier solution as well as the Bill-of-Material.

Multilevel switching significantly reduces the switching content of the output signal. Therefore, in most cases, eximo® amplifiers can drive speakers directly, without the use of an L-C filter – even in higher-powered applications. This enables ultra-compact solutions and design freedom in the target application.

* For smaller audio applications, such as mobile phones, an L-C filter is not required due to the low output power level of the audio amplifier.
 

Hear it Right

eximo® incorporates a high-order feedback topology to effectively suppress error sources that might cause audio quality degradation.

This ensures very low signal distortion as well as high robustness against non-ideal system conditions, such as power supply noise/ripple.
 

Do Not Disturb

Multilevel modulation schemes have lower EMI signal content than conventional class-D amplifiers. eximo® amplifiers are therefore easier to integrate in applications, without the need for significant filtering to combat unwanted interference.

eximo® Technology







eximo® amplifiers feature a unique power stage topology with more - but smaller - power transistors to create the amplified output. The power stage generates multilevel modulation patterns of up to five levels, thereby approximating the audio signal much closer than conventional class-D amplifiers.

Frequency multiplication is an inherent property of multilevel modulation, which essentially makes the effective switching frequency at the speaker load much higher than the switching frequency of the individual power transistors. This is utilized in eximo® amplifiers to significantly lower the switching activity, reducing the power losses associated with each switching event.

Multilevel switching also enables the reduction of – and in most cases, the complete elimination of – the large and costly L-C filter that is associated with conventional switching amplifiers.

eximo® amplifiers do not require variable power supply rails (aka class-G/H techniques) to achieve high power efficiency. However, if desired, a variable supply rail can easily be used with an eximo® amplifier.


The eximo® multilevel output stage offers great flexibility and allows for the configuring of the amplifier for optimal power performance in any application.

Via a digital control interface, various power modes can be defined by selecting the modulation method and the switching frequency.

During amplifier operation, the integrated power management algorithm automatically selects the most optimal power mode for a given power level. The seamless transition between power modes ensures that power losses are minimized across the entire output power range while ensuring high audio performance and low EMI.







eximo® amplifiers – as the world’s first and only integrated true multilevel audio amplifier technology – incorporate a 4th-order feedback loop. This guarantees excellent audio performance and a robustness against real-world system imperfections, such as a non-ideal power supply rail voltage.

The feedback loop is fully integrated on-chip. This minimizes the design-in effort by avoiding a time-consuming selection and optimization procedure of the external loop filter components, for achieving loop stability and satisfactory performance.










Several integrated protection features ensure that both amplifier and speakers are protected from potential damage during various fault events. This includes over-current protection circuits, on-chip temperature sensors and under-voltage supply monitors.

In general, eximo® amplifiers are designed to keep playing music for as long as possible and only shut down in the event of a non-recoverable error.

All warning and error signals are stored in registers that can be read via the amplifier control bus. A dedicated error pin is also available for hardware error signalling.

About Merus Audio

Our ambition is to create audio amplifier solutions that maximize output power, audio performance and design freedom – and minimize everything else.
 
We believe …
 - amplifiers should produce sound in your speakers, not heat to your surroundings.
 - amplifiers should be heard, not seen. Smaller and lighter is better. Bulky and heavy is history.
 - amplifiers must be robust and flexible, not delicate and demanding.
 
By challenging conventional wisdom we are creating cooler, smaller, lighter and better sounding amplifiers – for the benefit of all who love audio.
