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.
