Low-Voltage, 4Ω, Quad, SPST,
CMOS Analog Switches
The MAX4651/MAX4652/MAX4653 are low on-resis-
tance, low-voltage analog switches that operate from a
single +1.8V to +5.5V supply. CMOS switch construc-
tion allows processing analog signals that are within the
supply voltage range (GND to V+).
Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maxi-
mum ratings because stresses beyond the listed rat-
ings can cause permanent damage to the devices.
Always sequence V+ on first, followed by the logic
inputs, NO or COM. If power-supply sequencing is not
possible, add two small signal diodes (D1, D2) in series
with the supply pins for overvoltage protection (Figure
1). Adding these diodes reduces the analog signal by
one diode drop below V+ and one diode drop above
GND, but does not affect the devices’ low switch resis-
tance and low leakage characteristics. Device opera-
tion is unchanged, and the difference between V+ and
GND should not exceed 6V.
Although it is not required, power-supply bypassing
improves noise margin and prevents switching noise
from propagating from the V+ supply to other compo-
nents. A 0.1µF capacitor connected from V+ to GND is
adequate for most applications.
