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.

The class-D audio amplifier is much more efficient than a class-AB amplifier because the output MOSFETs switch from very high impedance to very low impedance, operating nanoseconds in the active ...

Class AB dissipates 70W of heat versus 5W for Class D—a 14-fold difference. Multiply this by two or more channels and heat management becomes an even greater design issue.

The big advantage with Class D amplifiers is that they're much more efficient from an energy usage point of view than conventional Class AB amplifiers, which are what you've seen in most audio ...

The type of amp you choose can have a huge effect on sound quality, power consumption, and cost. Here's how the Yamaha A-S301 performs.

Class D amplification is commonly used in portable devices for its power efficiency advantages over conventional Class AB amplifiers. Its primary disadvantage is its inherent generation of EMI ...

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

“With 78dB PSRR, the Class D LM4673 has PSRR approaching that of fully differential Class AB amps,” he said. The main difference between the LM4673 and LM4674 amplifiers is that the LM4673 is a single ...
