FSA2276UMX Product Details

The FSA2276UMX is a high-performance, Double-Pole Double-Throw (DPDT) analog switch with negative swing audio capability. The FSA2276UMX feature ultra-low audio RON of 0.5Ώ (typical) at 1.8V VDD. The FSA2276UMX operates over a VDD range of 1.65 V to 5.5 V, is fabricated with sub-micron CMOS technology to achieve fast switching speeds, and is designed for break-before-make operation. To minimize pop and click during operation, the turn on ramp time is selectable using an external capacitor (C_EXT). The FSA2276UMX features THD+N specifications that target a Hi-Fidelity audio quality into both 32 Ω headphones and line out type loads (>600 Ώ).


  • VDD Operating Range: 1.65 to 5.5 V
  • External Capacitor Connection for Pop and Click
  • Noise Suppression
  • Power-Off Protection on Common Ports
  • RON = 0.5 Ώ (Typ.) at 1.8 V
  • THD+N = -115 dB; 2 VRMS, 20 kΏ Load; f = 1 kHz
  • XTALK = -122 dB at 1 VRMS, 50 Ώ Load; f = 1 kHz
  • Off Isolation = -115 dB at 1 VRMS, 50 Ώ Load; f = 1 kHz
  • 12-Lead UMLP 1.8 mm x 1.8 mm


  • This product is general usage and suitable for many different applications.
