Analog Switch Single DPDT 12-Pin UMLP T/R

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 0.5O (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 O headphones and line out type loads (>600 O).
