GENERAL DESCRIPTION
The ADG811/ADG812 are low voltage complementary
metal-oxide semiconductor (CMOS) devices containing four
independently selectable switches. These switches offer an ultralow
on resistance of less than 0.8 Ω over the full temperature range.
The digital inputs can handle 1.8 V logic with a 2.7 V to 3.6 V
supply.
These devices contain four independent single-pole/single-throw
(SPST) switches. The ADG811 and ADG812 differ only in that
the digital control logic is inverted. The ADG811 switches are
turned on with a logic low on the appropriate control input, while
a logic high is required to turn on the switches of the ADG812.
Each switch conducts equally well in both directions when on
and has an input signal range that extends to the supplies.
