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.
PRODUCT HIGHLIGHTS 1. <0.8 Ω over full temperature range of –40°C to +125°C.
2. Single 1.65 V to 3.6 V operation.
3. Operational with 1.8 V CMOS logic.
4. High current handling capability (300 mA continuous
current at 3.3 V).
5. Low THD+N (0.02% typ).

ABSOLUTE MAXIMUM RATINGS
Table 4. TA = 25°C, unless otherwise noted Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those listed in the operational sections
of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability. Only one absolute maximum rating may be
applied at any one time.
Overvoltages at IN, S, or D are clamped by internal diodes. Current should be
limited to the maximum ratings given.

ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
