Class-D Audio Amplifiers

Analog Devices is a leader in Class-D audio amplifiers and audio signal processing, and we deliver audiophile-level performance with our proven analog and digital technology. We offer a wide range of audio amplifiers, including industry-leading microphone preamps, microphone drivers, line drivers, and receivers. Our Class-D amplifiers, in particular, are among the lowest power and lowest distortion in the industry. Our portfolio includes Class-A, Class-B, and Class-D audio amplifier offerings, along with a breadth of power ICs. Analog Devices amplifier products have been used in many high volume consumer products where the highest audio quality is expected. The lowest power consumption also enables this performance in many battery powered applications as well.
