General Description

The MAX4695 is a low-voltage, dual single-pole/double-

throw (SPDT) analog switch that operates from a single

+1.8V to +5.5V supply. The MAX4695 features break-

before-make switching action with a t

= 30ns and

OFF

= 18ns at +3V.

When powered from a +2.7V supply, the device has a

60Ω (max) on-resistance (R

), with 3Ω (max) R

matching and 10Ω (max) R

flatness. The digital logic

inputs are 1.8V-logic compatible from a +2.7V to +3.3V

supply. The MAX4695 is available in both a space-sav-

ing 3mm x 3mm 12-pin TQFN package and a

10-pin µMAX

package.

9-2044; Rev 1, 2/05 Low-Voltage, 60Ω Dual SPDT Analog Switch in Thin QFN Features The MAX4695 is a low-voltage, dual single-pole/doublethrow (SPDT) analog switch that operates from a single +1.8V to +5.5V supply. The MAX4695 features breakbefore-make switching action with a tON = 30ns and tOFF = 18ns at +3V. When powered from a +2.7V supply, the device has a 60Ω (max) on-resistance (RON), with 3Ω (max) RON matching and 10Ω (max) RON flatness. The digital logic inputs are 1.8V-logic compatible from a +2.
