General Description

The MAX4541–MAX4544 are precision, dual analog

switches designed to operate from a single +2.7V to +12V

supply. Low power consumption (5µW) makes these parts

ideal for battery-powered equipment. These switches offer

low leakage currents (100pA max) and fast switching

When powered from a +5V supply, the MAX4541–

MAX4544 offer 2

Ω max matching between channels, 60Ω

These switches also offer 5pC max charge injection and

a minimum of 2000V ESD protection per Method 3015.7.

The MAX4541/MAX4542/MAX4543 are dual single-pole/

single-throw (SPST) devices and the MAX4544 is a single-

pole/double-throw (SPDT) device. The MAX4541 has two

normally open (NO) switches and the MAX4542 has two

normally closed (NC) switches. The MAX4543 has one NO

and one NC switch and can be used as an SPDT, while

the MAX4544 is an SPDT. The MAX4541/MAX4542/

MAX4543 are available in tiny SOT23-8 and QFN-8 pack-

ages, and the MAX4544 is available in a SOT23-6 package.
