General Description

The MAX4751/MAX4752/MAX4753 are low on-resistance,

low-voltage, quad, single-pole/single-throw (SPST) analog

switches that operate from a single +1.6V to +3.6V sup-

ply. These devices have fast switching speeds (t

30ns, t

OFF

= 25ns), handle rail-to-rail analog signals, and

consume less than 1µW of quiescent power. The

MAX4753 has break-before-make switching.

When powered from a +3V supply, the MAX4751/

MAX4752/MAX4753 feature low 0.9Ω (max) on-resis-

tance (R

), with 0.12Ω (max) R

matching and 0.1Ω

(max) R

flatness. The digital input is 1.8V CMOS

compatible when using a single +3V supply.

The MAX4751 has four normally open (NO) switches,

the MAX4752 has four normally closed (NC) switches,

and the MAX4753 has two NO and two NC switches.

The MAX4751/MAX4752/MAX4753 are available in

3mm



3mm, 16-pin QFN and 14-pin TSSOP packages.

MAX4751/MAX4752/MAX4753 0.9Ω, Low-Voltage, Single-Supply Quad SPST Analog Switches Detailed Description The MAX4751/MAX4752/MAX4753 are low 0.9Ω max (at V+ = 3V) on-resistance, low-voltage quad analog switches that operate from a +1.6V to +3.6V single supply. CMOS construction allows switching analog signals that are within the supply voltage range (GND to V+). When powered from a +3V supply, the 0.9Ω (max) RON allows high continuous currents to be switched in a variety of applications.
