General Description

The MAX4736 is a low on-resistance, low-voltage, dual

single-pole/double throw (SPDT) analog switch that oper-

ates from a single 1.6V to 4.2V supply. This device has

fast switching speeds (t

= 25ns, t

OFF

= 20ns max),

handles rail-to-rail analog signals, and consumes less

than 4μW of quiescent power. The MAX4736 has break-

before-make switching.

When powered from a 3V supply, the MAX4736 features

low 0.6Ω on-resistance (R

), with 0.1Ω R

matching

and 0.05Ω R

flatness. The digital logic input is 1.8V

CMOS compatible when using a single 3V supply.

The MAX4736 has one normally open (NO) switch and

one normally closed (NC) switch, and is available in

12-pin TQFN-EP (3mm x 3mm), QFN-EP (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.
