Low-Voltage, 60Ω Dual SPDT Analog Switch in Thin QFN
General Description
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.
7V to +3.
3V supply.
The MAX4695 is available in both a space-saving 3mm x 3mm 12-pin TQFN package and a 10-pin µMAX® package.
