Hi-Fi Audio Switch w/ Negative Swing ON Semiconductor Hi-Fi Audio Switch is a high-performance, Double-Pole Double-Throw (DPDT) analog switch with negative swing audio capability. The FSA2275 and FS2276 feature ultra-low audio RON of 0.5Ω (typical). FSA2275 operates over a 2.5-5.5V VCC range and FSA2276 over 1.65 to 5.5V VCC. The series is fabricated with sub-micron CMOS technology to achieve fast switching speeds. It's designed for break-before-make operation. The turn on ramp time is selectable using an external capacitor (C_EXT) to minimize pop and click during operation. The FSA2275 and FSA2276 Hi-Fi Audio Switches feature THD+N specifications that target a Hi-Fidelity audio quality into both 32Ω headphones and line out type loads (>,600Ω).Learn More
