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 0.4Ω
(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.
