GENERAL DESCRIPTION
Figure 2.
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.
