General Description
The MAX4601/MAX4602/MAX4603 quad 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 current is only 2.5nA maximum at T
A
= +85°C.
These analog switches are ideal in low-distortion appli-
cations and are the preferred 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 mechanical relays.
The MAX4601 has four normally closed (NC) switches,
the MAX4602 has four normally open (NO) switches, and
the MAX4603 has two NC and two NO switches.
These switches operate from a single supply of +4.5V
to +36V or from dual supplies of ±4.5V to ±20V. All dig-
ital inputs have +0.8V and +2.4V logic thresholds,
ensuring TTL/CMOS-logic compatibility when using
±15V or a single +12V supply.
