Things to Consider When Choosing a Class D Amplifier

Class D amplifiers are the latest trend in home stereo systems. While this type of amplifier has some disadvantages, it is gaining popularity for many reasons. Some of the advantages of a class d amp include its compact size and high efficiency. The disadvantages, however, are outweighed by the benefits. Below are a few things to consider when choosing a class d amp. This type of amp is best suited for home stereo systems.

Noise-reduction circuits are essential for high-quality audio reproduction. Noises such as pops and clicks are annoying and can compromise the performance of an amplifier. To minimize the noises caused by Class D amplifiers, it is necessary to pay close attention to the state of the modulator, output-stage timing, and LC filter when muted. Noise-reduction designs should achieve a signal-to-noise ratio of at least 90 dB for low-power portable applications, while a higher value for high-power models is recommended. The individual noise sources must be tracked during the amplifier design process.

The most common topology of a Class D amplifier involves a triangle wave. When the input signal exceeds the triangle wave, the amplifier’s output is positive. When the signal falls below this value, it goes negative. This results in a series of pulses, known as pulse-width modulation. The higher the switching frequency, the more accurate the pulse width. But it will also make the amplifier less efficient. If you are looking for the best value for your money, look no further than the NuForce Amplifier.
