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(0.22ΩMAX)between switches and guarantees excellent on-resistance flatness over all signal range(0.22ΩMAX).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 TQFN-1.8×1.4-10L package.It operates over an ambient temperature range of-40℃to+85℃.
