Description
The FSA2270 is a high-performance, dual Single-Pole
Double-Throw (SPDT) analog switch with negative swing
audio capability. The FSA2270 features ultra-low R_ON of
0.4Ω (typical) at 3.0V V_CC. The FSA2270 operates over a
wide V_CC 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 FSA2270 features very low quiescent current even
when the control voltage is lower than the V_CC 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.”
