Double-Throw (SPDT) analog switch with negative swing audio capability. The FSA2269 features ultra-low RON of 0.4O (typical) at 3.0V V_CC. The FSA2269 operates over a wide V_CC range of 1.65V to 4.3V, is fabricated with submicron 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_CC 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.”
