1.25Ω, Dual SPST,
CMOS Analog Switches
General Description
Features
The MAX4580/MAX4590/MAX4600 dual analog switches
feature low on-resistance of 1.25Ω max. On-resistance is
matched between switches to 0.25Ω max and is flat
(0.3Ω max) over the specified signal range. Each switch
can handle Rail-to-Rail^® analog signals. The off-leakage
current is only 2.5nA max at +85°C. These analog
switches are ideal in low-distortion applications and are
the preferred solution over mechanical relays in automat-
ic 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 MAX4580 has two NC (normally closed) switches,
the MAX4590 has two NO (normally open) switches,
and the MAX4600 has one NC (normally closed) and
one NO (normally open) switch.
These switches operate from a +4.5V to +36V single
supply or from ±4.5V to ±20V dual supplies. All digital
inputs have +0.8V and +2.4V logic thresholds, ensuring
TTL/CMOS-logic compatibility when using a +12V sin-
gle supply or ±15V dual supplies.
