GENERAL DESCRIPTION

The ADG811, ADG812, and 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, and ADG813 are fully specified for

3.3 V, 2.5 V, and 1.8 V supply operation. They are available in a

16-lead TSSOP package.
