1.25Ω, Dual SPST,
CMOS Analog Switches
General Description
The MAX4680/MAX4690/MAX4700 dual analog switches
feature low on-resistance of 1.25Ω max. On-resistance is
matched between switches to 0.3Ω max 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.
