The FSA2275A is a high-performance, Double-Pole Double-Throw DPDT analog switch with negative swing audio capability. The FSA2275A features ultra-low audio RON of 0.5 Ώ typical at 2.5 V V. The FSA2275A operates over a V 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 FSA2275A features THD+N specifications that target a Hi-Fidelity audio quality into both 32 Ω headphones and line out type loads >600 ΩThe FSA2275A removes the shunt resistors which improve noise immunity.
