MAX4695ETC+

P1-P3P4-P6P7-P9P10-P11
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
ON
= 30ns and
t
OFF
= 18ns at +3V.
When powered from a +2.7V supply, the device has a
60Ω (max) on-resistance (R
ON
), with 3Ω (max) R
ON
matching and 10Ω (max) R
ON
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 1: Signals on IN_, COM_, NO_, and NC_ exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to
maximum current rating.
