Overview

The FSA2275 is a high-performance, Double-Pole Double-Throw (DPDT) analog switch with negative swing audio capability. The FSA2275 features ultra-low audio RON of 0.5Ω (typical) at 2.5 V VCC. The FSA2275 operates over a VCC range of 2.5 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 FSA2275 features THD+N specifications that target a Hi-Fidelity audio quality into both 32 Ω headphones and line out type loads (>600 Ω).

  • This product is general usage and suitable for many different applications.
  • VDD Operating Range: 2.5 to 5.5 V
  • External Capacitor Connection for Pop and Click noise suppression
  • Power-Off Protection on Common Ports
  • RON = 0.5 Ω (Typ.) at 2.5 V VDD
  • THD+N = -105 dB; 2 VRMS, 20 kΩ Load; f=1 kHz
  • XTALK = -134 dB at 1 VRMS, 50 Ω Load; f = 1 kHz
  • Off Isolation = -103 dB at 1 VRMS, 50 Ω Load; f = 1 kHz
  • 12-Lead UMLP 1.8 mm x 1.8 mm

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
