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 D amplifiers need bigger packages to have a low thermal resistance between the junction and PCB or heatsink. Manufacturers need to provide either small heatsinks or multilayered PCBs to realize ...

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 ...

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 ...

Sponsored by Texas Instruments: With more electronics being installed behind the dashboard, space is at a premium, which has engineers turning to compact, efficient Class-D amps ...
