SGM3718 0.6Ω Ultra Low On-Resistance, Negative Signal Passing, Dual SPDT Analog Switch

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.
