Low-Voltage, Single-Supply
Dual SPST/SPDT Analog Switches
General Description
____________________________Features
ꢀ Low R : 60Ω max (33Ω typ)
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

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.
