SGM2268_15 Datasheet, PDF (1/11 Pages) SG Micro Corp – Ultra Low ON-Resistance Dual, SPDT Analog Switch

SGM2268
0.4Ω Ultra Low ON-Resistance,
Dual, SPDT Analog Switch
GENERAL DESCRIPTION
The SGM2268 is a dual single-pole/double-throw
(SPDT) analog switch that is 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 Green TQFN-1.8×1.4-10L
package.
