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

= +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.
