Description
The FSA2269 is a high-performance, dual Single-Pole Double-Throw (SPDT) analog switch with negative swing audio capability. The FSA2269 features ultra-low RON of 0.4 (typical) at 3.0 V VCC. The FSA2269 operates over a wide VCC range of 1.65 V to 4.5 V, 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 VCC 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...
