ADG621/ADG622/ADG623 are CMOS ±5 V/+5 V, 4 Ω Dual SPST Switches. They feature 5.5 Ω (maximum) on resistance, 0.9 Ω (maximum) on resistance flatness, 2.7 V to 5.5 V single supply, ±2.7 V to ±5.5 V dual supply, rail-to-rail operation, 10-lead MSOP package, typical power consumption (<0.01 μW), TTL-/CMOS-compatible inputs. They can be used in Automatic test equipment, Power routing, Communication systems, Data acquisition systems, Sample-and-hold systems, Avionics, Relay replacements, Battery-powered systems.
The ADG621, ADG622, and ADG623 are monolithic CMOS single‑pole single‑throw (SPST) switches offered in a 10‑lead MSOP package. They feature low on‑resistance (typical 4 Ω), low power dissipation, rail‑to‑rail operation, and are available with either dual (+2.7 V to +5.5 V) or single (+2.7 V to +5.5 V) supply configurations. Applications include automatic test equipment, power routing, communication systems, data acquisition, avionics, and relay replacements.
The document includes a functional block diagram, pin configuration, detailed electrical specifications, typical performance curves, absolute maximum ratings, and an ordering guide with part numbers for each device variant. It also defines terminology used throughout the specifications.
