Low-Voltage, 4Ω, Quad, SPST,
CMOS Analog Switches
General Description
Features
The MAX4651/MAX4652/MAX4653 quad analog switch-
o On-Resistance
4Ω max at 5V
7Ω max at 3V
es feature 4Ω max on-resistance (R ) when operating
ON
from a single +5V supply. R
is matched between
ON
switches to 0.2Ω (max) and is flat (0.8Ω max) over the
specified signal range. Each switch can handle Rail-to-
Rail® analog signals. Off-leakage current is 0.1nA at
+25°C. These switches are ideal in low-distortion appli-
cations and are the preferred solution over mechanical
relays in automated 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.
o On-Resistance Flatness
0.8Ω max at 5V
2.5Ω max at 3V
o On-Resistance Matching
0.2Ω max (+2.7V to +5.5V)
o +1.8V to +5.5V Single-Supply Voltage
o +1.8V Operation
On-Resistance 30Ω (typ) Over Temperature
20ns typ, t 12ns (typ)
The MAX4651/MAX4652/MAX4653 operate from a sin-
gle +1.8V to +5.5V supply, making them ideal for use in
battery-powered applications.

The MAX4651 has four normally closed (NC) switches,
the MAX4652 has four normally open (NO) switches,
and the MAX4653 has two NO and two NC switches.
These devices are available in 16-pin QFN, TSSOP and
SO packages, as well as 20-pin QFN package.
