Hang around in any of the many guitar or audiophile forums or discussion boards for long enough, and eventually you’ll come across the arguments over amplifier topologies. One of the more interesting ...

TPA3122D2 IC is used as a class D audio amplifier and can deliver up to 15W of power at 10% distortions. The real advantage of using a class D amp, especially TPA3122 is the fact that this IC doesn’t ...

For driving an antenna, efficient generation of a clean and stable signal is required for optimum performance of many systems. This paper focuses on methodologies to efficiently apply a pure, ...

Emitted EMI is a drawback to the switching topology of the Class D amplifier. Passive filtering can moderate EMI but adds cost and complexity to the end product. What other internal circuit design ...

Sponsored by: Texas Instruments. EMI often plagues the electronic systems pervading automobiles, particularly AM radio, but a novel class-D amplifier IC can help erase those issues. Embedded ...

Because pulse modulation output signals are either on or off, Class D amplifiers produce far less heat than analog amplifiers. Reaching efficiencies greater than 90% compared to only 50% for analog, ...

In one of [Hans Peter]’s many idle browsing sessions at a manufacturer’s website, he came across a very cool chip – a 10 Watt class D amplifier chip. After the sample order arrived, he quickly put ...

Analog Devices has created a pair of 22V stereo Class-D audio amplifier that idle at 6mA and shut-down to microamps. MAX98415A and MAX98425A are similar, and both including envelope tracking control ...

Class D amps from $130 to $50,000—pulling more ears into hi-fi without demanding you sell a kidney. Solid tech, serious power, and none of the usual overpriced fluff. Finally, affordable doesn’t sound ...

Alpine Electronics of America, Inc. is now shipping the new KTA-450 Power Pack amplifier. This compact amplifier boasts a smaller footprint than its predecessors and can connect to the new iLX-W650 ...
