GENERAL DESCRIPTION
The ADG621, ADG622, and the ADG623 are monolithic,
CMOS SPST (single-pole, single-throw) switches. Each switch
of the ADG621, ADG622, and 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 respectively. 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 offers low on-resistance of
4
, which is matched to within 0.25
between channels.
These switches also provide low power dissipation yet gives
high switching speeds. The ADG621, ADG622, and ADG623
are available in a 10-lead
μ
SOIC package.
