GENERAL DESCRIPTION The SGM3718 is a negative signal passing dual single-pole/double-throw （SPDT） analog switch that is designed to operate from a single +2.5V to +5V power supply. Targeted applications include battery powered equipment that benefit from SGM3718’s ultra low on-resistance （0.6Ω） and fast switching speeds （tON = 17ns， tOFF = 24ns）。 The SGM3718 has excellent on-resistance matching （0.22Ω MAX） between switches and guarantees excellent on-resistance flatness over all signal range （0.22Ω MAX）。 This ensures excellent linearity and low distortion when switching audio signals. The SGM3718 is a committed dual single-pole/doublethrow （SPDT） that consist of two normally open （NO） and two normally closed （NC） switches. This configuration can be used as a dual 2-to-1 multiplexer. The SGM3718 can pass -2V ground referenced signal with very low distortion. The SGM3718 is available in Green UTQFN- 1.8×1.4-10L package. It operates over an ambient temperature range of -40℃ to +85℃.
