CMOS Analog Switches
General Description
The MAX4607/MAX4608/MAX4609 dual 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 cur-
rent is only 2.5nA max at +85°C. These analog switches
are ideal in low-distortion applications and are the pre-
ferred 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 mechani-
cal relays.
The MAX4607 has two normally closed (NC) switches,
the MAX4608 has two normally open (NO) switches,
and the MAX4609 has one NC and one NO switch.
These switches operate from a single supply of +4.5V to
+36V or from dual supplies of ±4.5V to ±20V. All digital
inputs have +0.8V and +2.4V logic thresholds, ensuring
TTL/CMOS-logic compatibility when using dual ±15V or
a single +12V supply.

Note 1:
Signals on NC_, NO_, COM_, or IN_, exceeding V+ or V- will be clamped by internal diodes. Limit forward diode current to max-
imum current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
