The FSA2270 is a high-performance, dual Single-Pole
Double-Throw (SPDT) analog switch with negative swing
audio capability. The FSA2270 features ultra-low RON of
0.4Ω (typical) at 3.0V VCC. The FSA2270 operates over a
wide VCC range of 1.65V to 4.3V, is fabricated with submicron CMOS technology to achieve fast switching
speeds, and is designed for break-before-make
operation. The select input is TTL-level compatible.

- Charged Device Model (JEDEC: JESD22-A101)
The FSA2270 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.”
