One of my first jobs as an engineer was at Empire Scientific Corp. in Garden City, NY in 1972. This was a high-end audio company that made speakers, turntables and phonograph cartridges. We had some ...

A relatively new technology called the pure digital or Class-D amplifier has been introduced into the audio world. The Class-D architecture allows the input audio signal to stay in its digital format ...

Addressing the core issues of latency and integration in developing audio amplifiers for today’s smart cockpits.

The TIDA-00573 reference design provides a Class D based amplifier solution that allows it to be evaluated in the form factor of a typical Class AB amplifier. The design is optimized to mitigate ...

Fig 1. This shows the spectra of both waveforms when the Class D output is issuing silence (no audio, duty cycle = 50%) with a switching frequency of 333 kHz. Fig 2. The blue line shows the energy ...

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.

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.

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 Cherry Audio MEGAschino Mk2 Standard Edition Class D Amplifier is energy efficient, boasting SOTA specs and gobs of power output (>400wpc, 8 ohms). Is it worth the $6k price? Read our review. The ...
