19-1202; Rev 3; 8/02
Low-Voltage, Single-Supply
Dual SPST/SPDT Analog Switches
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
speeds (t
ON
= 150ns max, t
OFF
= 100ns max).
When powered from a +5V supply, the MAX4541–
MAX4544 offer 2Ω max matching between channels, 60Ω
max on-resistance (R
ON
), and 6Ω max R
ON
flatness.
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.
