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

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 ...

[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 ...

To demo this, [Afrotech] used TI’s TPA3122 class d amplifier chip. It’s a pretty cheap chip for being a 15 Watt stereo amplifier, and the circuit is simple enough to build on a breadboard.

Sincea Class D amplifier has an output that switches between on and off, thenoise created by that switching must be filtered out. "You just have tobe careful with the filter design and circuit ...

Nuvoton has released the NAU83U25YG, an automotive-grade Class-D audio amplifier designed for vehicle electronics ...

Innovative circuit design can help with this problem: For instance, a new four-channel class-D amplifier IC introduced in this article specifically takes on that challenge.

However, there are some intricate topology-related drawbacks associated with Class D amplifiers. One such drawback is the increased distortion that Class D IC amplifier designers need to overcome.

Diodes has introduced a 10+10W stereo Class-D audio amplifier with an anti-clipping circuit to avoid distortion at high volume settings and output spectrum-spreading to improve EMC. Called PAM8106, ...

Class-D-powered receivers are also available, and while they're frequently referred to as digital amplifiers, Class D amps are controlled by either analog or digital circuits.
