A Class D audio amplifier is basically a switching amplifier or PWM amplifier. There are a number of different classes of amplifiers. We will take a look at the definitions for the main ...

Spice model makes it easy to design with PWM amplifiersHigh-efficiency PWM amplifiers are displacing linear designs in many applications. You can design a constant-current or a constant-voltage PWM ...

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.

The MSA66 PWM amplifier integrates a differential amplifier on the input, allowing it to interface directly to the majority of motor-control chipsets. Described as a full bridge, four-quadrant PWM ...

There comes a time in every electronic designer’s life when, whether they know it or not, they need an analog filter in their design. If you’re coming from a digital background, where everything is ...

The switching amplifier, or class D amplifier, has risen quickly to prominence in consumer audio applications, from MP3 devices including mobile phone handsets to games consoles, LCD-TVs, and home ...

We often take wireless communications for granted, without considering the underlying complexity and technological barriers. It's worth taking a closer look at those aspects. Pulse width modulation ...

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 ...

NAD’s first fully digital amplifier is the industry’s first digital amp that performs as well or better than the “very best linear Class A or AB amplifiers” with Class D efficiency, product ...

The DIA2240 device is an automotive qualified high precision, bidirectional and zero-drift current sense amplifier with enhance PWN rejection. The device sense drops across the shunt resistor over a ...
