A new book authored by Robert N. Buono delves deeply into Class-D amplifiers, a crucial technology in audio designs. Buono ...

[Part 1 of this article provides an overview of Class D amplifiers, and offers answers on amplifier selection and Class D amplifier filter design.] What is a Zobel? A Zobel is an impedance matching ...

You can observe a Class D audio amplifier's output if you introduce the filter circuit in Figure 1 . Based on Maxim's MAX-9727 quad-audio-line driver, IC 1 , the circuit combines separate single-ended ...

To say that class D amplifiers can't radiate directly from the circuit board is a slight oversimplification. Unfortunate choices of switching components and drive circuits can lead to spectral output ...

Digital Amplification Basically, a digital (Class D) amplifier takes an incoming analog signal and converts it into a digital representation comprised of pulse widths. Although there are a number of ...

Class C amplifiers offer high efficiency (up to 90%), but the high-Q tank circuits needed for their operation have narrow bands of resonance.

If you have read an amplifier review or looked at the specifications for an amp, the chances are that you have come across a term such as 'Class A/B'. In fact, this is just one of a number of ...

Emitted EMI is a drawback to the switching topology of the Class D amplifier. Passive filtering can moderate EMI but adds cost and complexity to the end product. What other internal circuit design ...

In one of [Hans Peter]’s many idle browsing sessions at a manufacturer’s website, he came across a very cool chip – a 10 Watt class D amplifier chip. After the sample order arrive… ...

Class D amplifiers are superior to their predecessors in many ways, but none of them matter to music fans unless they sound good, too.
