Texas Instruments (www.ti.com) has introduced the TAS5414 and TAS5424, the first members of a new family of Class D amplifiers designed especially for automotive audio applications. Texas Instruments ...

Dallas — Texas Instruments Inc. (TI) developed its first digital amplifiers for the automotive market, which are based on its PurePath Class D amps for the home. Specifically designed for automotive ...

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, ...

Class D amps are simple – just take an input, and use that to modulate a square wave with PWM. Send this PWM signal to a MOSFET or something, and you have the simplest class D amp in existence.

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 ...

As Axiom’s chief R&D engineer Tom Cumberland describes it, a digital amplifier is a “power DAC”, and of course a DAC (Digital-to-Analog Converter) is the basis of all digitally recorded media, whether ...

This file type includes high resolution graphics and schematics when applicable. Class D audio amplifiers are able to fulfill the requirements for audio applications such as mobile handsets, Bluetooth ...

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, ...

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 ...

Just today I read on an internet forum a post by a "hot" new manufacturer of class D amplifiers saying that "the only way to solve the interference problem is to put the amplifier in a completely ...

Savant Systems LLC, having delivered the first Apple-based home automation and control system, has announced the introduction of a 16-channel class D amplifier for distributed audio applications.

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 ...
