1 Introduction

Analog muxes are used in electronic systems to control a specific transmission path for an analog signal. These devices are used in a wide variety of applications, including audio and high-speed interface and video systems. However, every specific application requires the mux to be optimized for different parameters. This application note describes some important analog-mux parameters, such as on-resistance (RON), RON flatness, and bandwidth. Application-specific muxes are presented for:

  • Video
  • Hi-Speed interface USB
  • HDMI
  • DisplayPort
