The ADG619/ADG620 are monolithic CMOS single-pole double-throw (SPDT) switches. Each switch conducts equally well in both directions when the device is on. The ADG619/ADG620 offer a low on resistance of 4 Ω, which is matched to the input impedance of many analog circuits.
The ADG619 and ADG620 are monolithic CMOS single‑pole double‑throw (SPDT) switches offered in 8‑lead SOT‑23 and MSOP packages. They provide low on‑resistance (typical 4 Ω) and low power dissipation, suitable for applications such as automatic test equipment, power routing, and avionics.
The devices support dual‑supply (+2.7 V to 5.5 V) or single‑supply (2.7 V to 5.5 V) operation, feature break‑before‑make (ADG619) or make‑before‑break (ADG620) switching, and include ESD protection. Detailed specifications, pin configurations, and performance curves are provided.
