1.25 / Dual SPST / CMOS Analog Switches
General DescriptionThe MAX4680/MAX4690/MAX4700 dual analog switches
feature low on-resistance of 1.25Ωmax. On-resistance is
matched between switches to 0.3Ωmax and is flat (0.3Ω
max) over the specified signal range. Each switch can
handle Rail-to-Rail®analog signals. Off-leakage current is
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.

ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
