MAX4736
0.6Ω, Low-Voltage, Single-Supply, Dual SPDT
Analog Switch
General Description
Benefits and Features
The MAX4736 is a low on-resistance, low-voltage, dual
single-pole/double throw (SPDT) analog switch that operates from a single 1.6V to 4.2V supply. This device has
fast switching speeds (tON = 25ns, tOFF = 20ns max),
handles rail-to-rail analog signals, and consumes less
than 4μW of quiescent power. The MAX4736 has breakbefore-make switching.
●● Low RON
0.6Ω (3V Supply)
1.5Ω (1.8V Supply)
When powered from a 3V supply, the MAX4736 features
low 0.6Ω on-resistance (RON), with 0.1Ω RON matching
and 0.05Ω RON flatness. The digital logic input is 1.8V
CMOS compatible when using a single 3V supply.
●● 1.8V CMOS Logic Compatible (3V Supply)
●● 0.1Ω max RON Flatness (3V Supply)
●● Single-Supply Operation Down to 1.6V
●● Available in TQFN, μDFN, and μMAX Packages
●● Fast Switching: tON = 25ns, tOFF = 20ns
Ordering Information
The MAX4736 has one normally open (NO) switch and
one normally closed (NC) switch, and is available in
12-pin TQFN (3mm x 3mm), 10-pin μMAX, and 10-pin
μDFN (2mm x 2mm) packages.

MAX4736
0.6Ω, Low-Voltage, Single-Supply, Dual SPDT
Analog Switch
Detailed Description
Logic Inputs
The MAX4736 is a low 0.8Ω max (at V+ = 2.7V) onresistance, low-voltage, dual SPDT analog switch that operates from a 1.6V to 4.2V single supply. CMOS switch
construction allows switching analog signals that range
from GND to V+.
The MAX4736 logic inputs can be driven up to 3.6V,
regardless of the supply voltage. For example, with a 1.8V
supply, IN_ can be driven low to GND and high to 3.6V.
Driving IN_ rail-to-rail minimizes power consumption.
When powered from a 2.7V supply, the 0.8Ω max RON
allows high continuous currents to be switched in a variety
of applications.
Analog signals that range over the entire supply voltage
(V+ to GND) can be passed with very little change in
onresistance (see Typical Operating Characteristics). The
switches are bidirectional, so the NO_, NC_, and COM_
pins can be used as either inputs or outputs.
Applications Information
Proper power-supply sequencing is recommended for all
CMOS devices. Do not exceed the absolute maximum
ratings; stresses beyond the listed ratings can cause permanent damage to the devices. Always sequence V+ on
first, followed by NO_, NC_, or COM_.
Although it is not required, power-supply bypassing
improves noise margin and prevents switching noise
propagation from the V+ supply to other components. A
0.1μF capacitor, connected from V+ to GND, is adequate
for most applications.
Analog Signal Levels
Layout
High-speed switches require proper layout and design
procedures for optimum performance. Reduce stray inductance and capacitance by keeping traces short and wide.
Ensure that bypass capacitors are as close to the device
as possible. Use large ground planes where possible.
