The most common audio power amplifier operates in the Class-AB mode. It provides the greatest amount of output power with the least amount of distortion. The downside is that it consumes quite a bit ...

A class-D puts out a pulse-width modulated (PWM) signal instead of the linear signal that is typical in class-AB amplifiers. The PWM signal contains the audio signal and the PWM switching frequency ...

Meylan, France - February 4, 2008 - The pressure to lowering the power consumption leads system designers to investigate different architectures for audio amplifiers. They naturally investigate ...

NXP Semiconductors N.V. has introduced two new automotive audio amplifiers supporting energy-saving start-stop systems – the TDF8530 and TDF8546. The TDF8530 is an ultra-efficient quad-channel Class-D ...

Class AB amplifiers have been around for a long time, and even with Class D designs becoming more common, there's still a reason many enthusiasts continue to gravitate toward AB amplification. Class D ...

Eindhoven, Netherlands: According to NXP, its two new audio amplifiers increase efficiency for energy-saving start-stop automotive systems. Both amps enable an uninterrupted audio experience during ...

Consumer demand for flexible audio features and hi-fi sound from mobile phones has led to handset audio chip designers having to optimise the Class D amplifier to meet the noise and power management ...

Technology has democratized the music industry in many obvious ways – notice how every band, regardless of stature, has a MySpace page? But one of technology's more subtle effects has been to make our ...

Analog amplifiers are cataloged by how much current flows during each wave cycle. Measured in degrees, 360º means current flows 100% of the time. The more current, the more inefficient and the more ...

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 ...

STMicroelectronics is using Class-G analogue audio technology to create 117dB S/N ratio, >117dB dynamic range (A-weighted), automotive amplifier. Class-G amplifiers are similar to traditional Class-AB ...
