1. What is an audio IC?
An audio IC is a miniature electronic device that integrates multiple electronic components on a silicon chip. It is responsible for processing and converting audio signals and amplifying them for speakers to play. Audio ICs can include multiple functions, such as sound decoders, amplifiers, mixers, and digital signal processors. Audio ICs are core components in modern electronic devices, responsible for processing and transmitting various electronic signals. Audio ICs play a vital role in sound systems, especially in audio processing and signal amplification.
