[Part 1 of this article provides an overview of Class D amplifiers, and offers answers on amplifier selection and Class D amplifier filter design.] What is a Zobel? A Zobel is an impedance matching ...

Other Class D amplifiers lack the clip-detection feature altogether, but you can implement it with external components. An analog-input Class D amplifier comprises PWM (pulse-width-modulation) logic, ...

This file type includes high resolution graphics and schematics when applicable. Class D audio amplifiers are able to fulfill the requirements for audio applications such as mobile handsets ...

To demo this, [Afrotech] used TI’s TPA3122 class d amplifier chip. It’s a pretty cheap chip for being a 15 Watt stereo amplifier, and the circuit is simple enough to build on a breadboard.

Sincea Class D amplifier has an output that switches between on and off, thenoise created by that switching must be filtered out. "You just have tobe careful with the filter design and circuit ...

However, there are some intricate topology-related drawbacks associated with Class D amplifiers. One such drawback is the increased distortion that Class D IC amplifier designers need to overcome.

The latter amplifier design utilizes an analog input signal with a switching power supply. Rotel has taken this analog-controlled Class D design a step further with the implementation of two important ...
