FSA2275 / FSA2275A — DPDT (0.5 ) HiFi Audio Switch w/ Negative Swing August 2016 FSA2275 / FSA2275A — DPDT (0.5 ) HiFi Audio Switch w/ Negative Swing Features  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  Removed R_SHUNT resistors for FSA2275A Applications  Mobile Phone, Tablet, Notebook PC, Media Player  Docking Station, TV, Set-Top Box, LCD Monitor Description The FSA2275 / FSA2275A is a high-performance, Double-Pole Double-Throw (DPDT) analog switch with negative swing audio capability. The FSA2275 / FSA2275A features ultra-low audio RON of 0.5  (typical) at 2.5 V VCC. The FSA2275 / FSA2275A 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 / FSA2275A features THD+N specifications that target a Hi-Fidelity audio quality into both 32 Ω headphones and line out type loads (>600 Ω). The FSA2275A removes the shunt resistors which improve noise immunity. Processor Audio Source 1 SEL MUTE ...
