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.
