The ADG811/ADG812/ADG813 are low voltage CMOS devices
containing four independently selectable switches. These switches
offer 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. The ADG813 contains two switches
whose digital control logic is similar to the ADG811, while the
logic is inverted on the other two switches.
Each switch conducts equally well in both directions when on
and has an input signal range that extends to the supplies. The
ADG813 exhibits break-before-make switching action.
The ADG811/ADG812/ADG813 are fully specified for 3.3 V,
2.5 V, and 1.8 V supply operation. The ADG811 is available in a
16-lead TSSOP package and a 16-lead LFCSP package, and the
ADG812/ADG813 are available in a 16-lead TSSOP package.
