You can generate a variable dc reference voltage with a DAC or with a PWM (pulse-width-modulation) signal from your controller (Figure 1). The accuracy of the voltage source that the ...

A motor-drive servo amplifier's output voltage has a fundamental frequency and amplitude that corresponds to the motor speed, torque, and number of motor poles. PWM amplifiers, by their nature, also ...

The switching amplifier, or class D amplifier, has risen quickly to prominence in consumer audio applications, from MP3 devices including mobile phone handsets to games consoles, LCD-TVs, and home ...

Virtually every electronic product today is digital, including products in the once all-analog domain of communications. Audio power amplification is about the last thing to be digitized. And thanks ...

When the world's first commercially available audio product using a digital amplifier appeared in 1998, it created quite a stir with its performance and ease of use. Digital amplifiers provide several ...
