Low-Voltage, 60Ω Dual SPDT Analog Switch in Thin QFN

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 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 12-pin TQFN (3mm x 3mm) package and a 10-pin µMAX® package.
