    SGM2268

    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 (0.4?) and fast switching speeds.

    The SGM2268 features guaranteed on-resistance matching (0.04? TYP) between switches and guaranteed on-resistance flatness over the signal range (0.08? 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.

    The SGM2268 is available in a Green TQFN-1.8×1.4-10L package.
