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. Off-
leakage current is only 5nA max at T
A
= +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 require-
ments, 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 fea-
tures guaranteed break-before-make switching.
These devices operate from a single +4.5V to +36V sup-
ply 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.
