Description
The FSA2270T is a high-performance, dual Single-Pole
Double-Throw (SPDT) analog switch with negative swing
audio capability. The FSA2270T features ultra-low RON of
0.4Ω (typical) at 3.0V VCC. The FSA2270T operates over
a wide VCC range of 1.65V to 4.3V, 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 FSA2270T 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 FSA2270T includes termination resistors that
improve noise immunity during overshoot excursions,
off-isolation coupling, or “pop-minimization.”
