The FSA2269 is a high-performance, dual Single-Pole Double-Throw (SPDT) analog switch with negative swing audio capability. The FSA2269 features ultra-low R. The FSA2269 operates over a wide V range of 1.65V to 4.5V, is fabricated with sub-micron CMOS technology to achieve fast switching speeds, and is designed for break-before-make operation. The select input is TTL-level compatible. The FSA2269 features very low quiescent current even when the control voltage is lower than the V supply. This feature suits mobile handset applications by allowing direct interface with baseband processor general-purpose I/Os with minimal battery consumption. The FSA2269TS includes termination resistors that improve noise immunity during overshoot excursions, off-isolation coupling, or "pop-minimization."
