A Class D audio amplifier is basically a switching amplifier or PWM amplifier. There are a number of different classes of amplifiers. We will take a look at the definitions for the main ...

If you’ve ever glanced at the specifications sheet for an amplifier, one of the things you may have noticed is the amplifier’s class. Typically denoted by a letter or two, the most common amplifier ...

Learn how power amplifiers work, the common types, and what to lookout for when shopping for amps. You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before ...

Analog amplifiers are cataloged by how much current flows during each wave cycle. Measured in degrees, 360º means current flows 100% of the time. The more current, the more inefficient and the more ...

A class-D puts out a pulse-width modulated (PWM) signal instead of the linear signal that is typical in class-AB amplifiers. The PWM signal contains the audio signal and the PWM switching frequency ...

Love Class A amplification but hate the heat associated with it? The Infigo Audio Method 6 offers a very different take. There are many ways to eat your Smarties and Infigo Audio believes that it has ...

Launched at CES 2005, a direct digital feedback technology from audio switching amplifier specialist Zetex Semiconductors sets new standards in digital amplifier sound quality. Named Class Z, this ...

A relatively new technology called the pure digital or Class-D amplifier has been introduced into the audio world. The Class-D architecture allows the input audio signal to stay in its digital format ...

We know Class D audio amplification offers advantages in efficiency and size for battery-powered devices. What you may not know, however, is that these advantages can now extend to amplifiers up to ...
