General Description
The FSA2271T is a high-performance, dual - single pole double throw (SPDT)
analog switch with negative swing audio capability. It features ultra-low
RON of 0.4W (typical) at 3.0V
VCC. The FSA2271T operates over a wide VCC 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 VCC 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.
