Class D audio amplifiers must switch efficiently at high frequency to deliver powerful, high fidelity sound from a compact automotive head unit, while keeping electromagnetic emissions low enough so as not to interfere with nearby radio and wireless systems.
Vishay enables the required compact power stage design with power MOSFETs for high frequency, low loss switching. Our inductors and ceramic and film capacitors form the output filters that remove switching noise from the audio signal and our resistors condition feedback loops for accurate, distortion-free amplification.
Behind the Class D audio amplifier is The DNA of tech.®
