General Description
The MAX4661/MAX4662/MAX4663 quad analog switches
feature low on-resistance of 2.5Ω max. On-resistance is
matched between switches to 0.5Ω max and is flat
(0.5Ω max) over the specified signal range. Each
switch can handle Rail-to-Rail®analog signals. Offleakage current is only 5nA max at TA= +85°C. These
analog switches are ideal in low-distortion applications
and are the preferred solution over mechanical relays in
automatic test equipment or applications where current
switching is required. They have lower power requirements, use less board space, and are more reliable
than mechanical relays.
The MAX4661 has four normally closed (NC) switches,
and the MAX4662 has four normally open (NO) switches.
The MAX4663 has two NC and two NO switches, and features guaranteed break-before-make switching.
These devices operate from a single +4.5V to +36V supply or from dual ±4.5V to ±20V supplies. A separate logic
supply pin guarantees TTL/CMOS-logic compatibility
when operating across the entire supply voltage range.

ABSOLUTE MAXIMUM RATINGS
Stresses 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.
