FSA2276: DPDT (0.5 Ώ) HiFi Audio Switch w/ Negative Swing

The FSA2276 is a high-performance, Double-Pole Double-Throw (DPDT) analog switch with negative swing audio capability. The FSA2276 feature ultra-low audio RON of 0.5Ώ (typical) at 1.8V VDD. The FSA2276 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 FSA2276 features THD+N specifications that target a Hi-Fidelity audio quality into both 32 Ω headphones and line out type loads (>600 Ώ).
