  • 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: 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...

  • Re: Pulsed High Voltage Current Sources for 600V and 1200V

    The schematic with the MOSFET and 1100V is very interesting. It should be possible to do something about the HV drive requirement. There is where a small pentode or beam power tube might stand the voltage and be reasonably linear as a voltage amp for the MOSFET. I still use vacuum tubes for the out...

22-W Mono Automotive Digital Audio Amplifier

The TAS5421-Q1 is a mono digital audio amplifier, ideal for use in automotive emergency call (eCall), telematics, instrument cluster, and infotainment applications. The device provides up to 22 W into 4 Ω at less than 10% THD+N from a 14.4-Vdc automotive battery. The wide operating voltage range and excellent efficiency make the device ideal for start-stop support or running from a backup battery when required. The integrated load-dump protection reduces external voltage clamp cost...

Class-D audio power amplifier with speaker

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...
