Maxim Integrated’s new MAX98390 smart amplifier isn’t just another audio IC. It goes way beyond the expectations of most audio design engineers. This class D amplifier, which delivers high efficiency in battery-operated devices, adds many new features and capabilities not available elsewhere. If you’re designing portable equipment with an audio capability, the device may be a welcome alternative.
As consumer products continue to shrink, the desire to include audio hasn’t abated. Speakers have become smaller to accommodate this need, leading to a decline in audio quality. The most affected characteristics have been loudness and bass.
