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

At lower inputs Class D dissipation decreases, while for Class AB it increases. How does this relate to real life, when the amplifier is used for music or speech? This is best simulated using noise ...

Class AB amplifiers have been the low-cost workhorse solution, but they have significant power dissipation issues and thus require large heatsinks. Class D amplifiers are known for having better ...

A Class-D type output stage (PWM switching) enables a higher efficiency than a class-AB amplifier: no doubt about it. For applications requiring an output power in the Watt range, Class-D limited ...

Class D amps can achieve efficiencies as high as 90%, with distortion levels approaching class AB. A drawback of Class D concerns the challenging task of suppressing radiated and conducted ...

In market for a powerful 200 WPC amp? ATI has you covered with two completely different technologies. We compare the AT4000 class A/B and the AT522NC Class-D amplifiers to help you decide.

Trade offs in designing with IC and discrete component class D amplifiers including switching speeds, filtering options, and power supply considerations.

Knowing what the Class AB label means for the Yamaha A-S301 makes it easier to determine if it's right for your sound goals. Customer reviews can help out with this as well.
