  • Performance and Reliability Improvements in High-Power Class D Audio Amplifier Design

    Class D systems are quickly narrowing audio performance gap with simpler, more efficient designs offering fidelity that can surpass that of analog amplifiers. But with higher fidelity comes increased complexity. This in-depth Silicon Labs white paper explores how to improve the performance

  • Audio Power Amplifier Design Handbook, Fourth Edition

    Audio Power Amplifier Design Handbook, Fourth Edition. Packed with unique insights into audio design and performance, as well as complete amplifier designs and schematics, this book takes you through the causes of distortion, measurement techniques, and design solutions to minimize distortion

  • Using SigLab for Production Line Audio Test

    The following are three typical audio. measurements on a stereo amplifier that will. be discussed. · channel to channel cross talk. · harmonic distortion. · signal to noise ratio. Other measurements that can

  • About Power Ratings

    to the load is not considered (we can't hear DC) and even avoided in the amplifier design since DC to a speaker can damage the speaker voice coil. With home audio amplifiers there is also no discussion, or rating, of the power dissipation capability of the amplifier or often even a rating

  • Servo Amplifier Tutorial

    The "Servo Amplifier" on-line tutorial reviews the operation of servo amplifiers used to drive DC and brushless motors. The complete tutorial with audio can be viewed at http://www.galilmc.com/training/webconf.html. The tutorial begins with a discussion of the power regulating methods, leading

  • Class H Amplifiers

    Class H amplifier operation takes the Class G amplifier design one step further and actually modulates the higher power supply voltage through the input signal. This allows the power supply to track the audio input and provide just enough voltage for optimum operation of the output devices

  • Re: Most Popular Open Source Design

    Most popular open source design is 'low TIM Leach amplifier'. If you want to NOT Waste the board and want pcb design artwork, you can google search images 'pcb artwork', and select a few that will be useful for some of you for personal DIY. The schematic will mostly be available in the link it appe...

  • Re: Circuit to Amplify Speaker Sound

    You could use a Tripath D-class amp. You can get these in kit-form, fully assembled boards or complete amps quite cheap on Ebay, or from people like 41hz , or you can get other kits (eg Velleman) from people like this . You could try googling something like "DIY PC amp schematic" and you'll find no...

  • Help With Electronics Project

    Here are the schematics of a 4 input/4 output amplifier circuit (link: http://www.zen22142.zen.co.uk/Circuits/Audio/quad.htm) to which I'm trying to connect this equalizer circuit (http://www.zen22142.zen.co.uk/Circuits/Audio/3band.htm). Is it necessary to build one equalizer for each input, or c...

  • Re: 12vdc 700a IN 16.5vac .5 a OUT Need To Build

    I am serious about the car audio amplifier application. You can find complete DIY kits or just schematics with a simple Google search. Just adding a simple 60 Hz oscillator (Colpitts?) to the input of the amplifier and bingo your entire supply conundrum is solved. I'm bothered with your insistence f...

  • Re: Commercial Radio Station Being Picked Up On 447.2375 MHz

    Joshi, perhaps you can explain to us how you would tell the difference between the feed and the broadcast signal, especially since they are identical except for the carrier frequency, power level and a few microseconds of delay as the signal is amped up to broadcast levels. And let's rule out...

TAS2552 Class-D audio power amplifier

The TAS2552 is a high efficiency Class-D audio power amplifier with advanced battery current management and an integrated Class-G boost converter. The device constantly measures the current and voltage across the load and provides a digital stream of this information. The Class-G boost converter generates the Class-D amplifier supply rail. During low Class-D output power, the boost improves efficiency by deactivating and connecting VBAT directly to the Class-D amplifier supply. When high power...
