General Description

The MAX4601/MAX4602/MAX4603 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. The off-

leakage current is only 2.5nA maximum at T

= +85°C.

These analog switches are ideal in low-distortion appli-

cations and are the preferred solution 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 MAX4601 has four normally closed (NC) switches,

the MAX4602 has four normally open (NO) switches, and

the MAX4603 has two NC and two NO switches.

These switches operate from a single supply of +4.5V

to +36V or from dual supplies of ±4.5V to ±20V. All dig-

ital inputs have +0.8V and +2.4V logic thresholds,

ensuring TTL/CMOS-logic compatibility when using

±15V or a single +12V supply.

MAX4601/MAX4602/MAX4603 2.5Ω, Quad, SPST, CMOS Analog Switches Applications Information Overvoltage Protection Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings can cause permanent damage to the devices. Always sequence V+ on first, then V-, followed by the logic inputs, NO, or COM.
