Analog Switches | FSA2271T

The FSA2271T is a high-performance, dual - single pole double throw (SPDT) analog switch with negative swing audio capability. It features ultra-low R_ON of 0.4Ω (typical) at 3.0V V_CC. The FSA2271T operates over a wide V_CC range of 1.65V to 4.3V and is fabricated with sub-micron CMOS technology to achieve fast switching speeds. Designed for break-before-make operation, the FSA2271T select input is TTL level compatible. The FSA2271T features very low quiescent current, even when the control voltage is lower than the V_CC supply. This feature is optimized for the mobile handset applications, allowing direct interface with baseband processor general-purpose I/Os with minimal battery consumption. The FSA2271T includes termination resistors that improve noise immunity during overshoot excursions, “pop-minimization,” or off-isolation coupling.
