The SGM5223 is a dual single-pole/double-throw
(SPDT) analog switch designed to operate from a single
+1.8V to +4.2V power supply. Targeted applications
include battery powered equipment that benefit from
SGM5223’s low ON-resistance (0.5Ω) and fast
switching speeds (t
ON
= 17ns, t
OFF
= 27.5ns).
SGM5223 has excellent on-resistance matching (0.18
Ω
max) between switches and guarantees excellent on-resistance
flatness over all signal range (0.1Ω TYP). This ensures
excellent linearity and low distortion when switching
audio signals.
The SGM5223 is a committed dual single-pole/double
-throw (SPDT) that consist of two normally open (NO)
and two normally close (NC) switches. This
configuration can be used as a dual 2-to-1 multiplexer.
SGM5223 is available in Pb-free WQFN-10 package.
