ADG621 CMOS ±5 V/+5 V, 4 Ω Dual SPST Switch

Low on resistance, RON (4 Ω typical). Dual ±2.7 V to ±5.5 V or single +2.7 V to +5.5 V. Low power dissipation; CMOS construction ensures low power dissipation. Tiny 10-lead MSOP package. Applications Automatic test equipment Power routing Communication systems Data acquisition systems Sample-and-hold systems Avionics Relay replacements Battery-powered systems

The ADG621/ADG622/ADG623 are monolithic, CMOS, single-pole, single-throw (SPST) switches. Each switch of the ADG621/ADG622/ADG623 conducts equally well in both directions when on.

The ADG621/ADG622/ADG623 contain two independent switches. The ADG621 and ADG622 differ only in that both switches are normally open and normally closed. In the ADG623, Switch 1 is normally open, and Switch 2 is normally closed. The ADG623 exhibits break-before-make switching action.

The ADG621/ADG622/ADG623 offer low on resistance of 4 Ω, which is matched to within 0.25 Ω between channels. These switches also provide low power dissipation yet give high switching speeds. The ADG621/ADG622/ADG623 are available in a 10-lead MSOP package.
