Product Introduction

Overview

The FSA2275AUMX is a high-performance, Double-Pole Double-Throw (DPDT) analog switch designed by onsemi. It is notable for its negative swing audio capability, making it suitable for high-fidelity audio applications. The device operates over a wide voltage range of 2.5 V to 5.5 V and is fabricated using sub-micron CMOS technology, ensuring fast switching speeds and low distortion.

Key Features

  • Ultra-low audio RON of 0.5 Ω (typical) at 2.5 V VCC
  • Break-before-make operation to prevent signal distortion
  • Selectable turn-on ramp time using an external capacitor (CEXT) to minimize pop and click noise
  • Power-off protection on common ports
  • High-fidelity audio quality suitable for both 32 Ω headphones and line out type loads (>600 Ω)
  • Sub-micron CMOS technology for fast switching speeds

Applications

The FSA2275AUMX is versatile and suitable for various audio applications, including:

  • High-fidelity audio systems
  • Audio switching in consumer electronics
  • Professional audio equipment
  • Headphone and line-out switching
  • General-purpose analog switching where low distortion and fast switching are required
