Designed for battery-operated portable devices, the MAX98500 boosted Class D amplifier integrates a boost converter to provide a constant output power and, therefore, louder audio output over a wide ...
This article was originally published in the Dec 14, 1998 issue of Electronic Design. Class-D audio power amplifiers (APAs) were first introduced nearly 50 years ago. Since then, they have been used ...
With class-D amplifiers, short-circuit faults in the output H-bridge result in dangerous current paths. This type of fault occurs when either the positive or negative outputs (OUTP or OUTN, ...
The efficiency and size advantages of Class D audio amplification in battery- powered devices are well known. These advantages are now extended to amplifiers up to 500W, made possible by solidstate ...
