SGM2268
GENERAL DESCRIPTION
The SGM2268 is a dual single-pole/double-throw
(SPDT) analog switch that designed to operate from a
single +1.8V to +4.2V power supply. Targeted
applications include battery powered equipment that
benefit from ultra low ON-resistance (0.4Ω) and fast
switching speeds.
SGM2268 features guaranteed on-resistance matching
(0.04Ω TYP) between switches and guaranteed on-
resistance flatness over the signal range (0.08Ω TYP),
as well as high Off-Isolation and low crosstalk. This
ensures excellent linearity and low distortion when
switching audio signals.
The SGM2268 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.
SGM2268 is available in Pb-free WQFN-10 package.
