315 Watt Class D Power Amplifier

315 w class D amplifier 300x176 315 Watt Class D Power AmplifierThis audio amplifier based? TAS5261 (bridge digital amplifier) has output power of 315 watts per channel and an efficiency up to 96% is suitable for use in a variety of Sound applications, such as home theater systems.
Reducing the cost and availability of high-bit ADC and digital signal processors have contributed to the emergence of high power amplifiers, D-class, based on pulse-width modulation. Work output transistor stages in a key mode of such amplifiers allows a few, sometimes dozens of times to increase efficiency, thereby reducing heat generation amplifier, its size and cost. Among all the audio amplifier device class D are the most cost-effective, thanks to the use of digital signal processing. It eliminates the possibility of distortion and noise in the pre-amplifier paths, streamlines and simplifies all kinds of linear and nonlinear signal conversion without using mechanical adjustment components, extends the functionality.
