General Description

The MAX4680/MAX4690/MAX4700 dual analog switches

feature low on-resistance of 1.25

Ω max. On-resistance is

matched between switches to 0.3

Ω max and is flat (0.3Ω

max) over the specified signal range. Each switch can

only 5nA max at +85°C. These analog switches are ideal

in low-distortion applications and are the preferred solu-

tion over mechanical relays in automatic test equipment

or applications where current switching is required. They

have low power requirements, require less board space,

and are more reliable than mechanical relays.

The MAX4680 has two NC (normally closed) switches,

and the MAX4690 has two NO (normally open) switch-

es. The MAX4700 has one NC and one NO switch and

features guaranteed break-before-make switching.

These devices operate from a +4.5V to +36V single

supply or from ±4.5V to ±20V dual supplies. A separate

logic supply pin guarantees TTL/CMOS-logic compati-

bility while operating across the entire supply voltage

range.
