Low-Voltage, 60鈩?Dual
SPDT Analog Switch in QFN
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
60鈩?(max) on-resistance (R
ON
), with 3鈩?(max) R
ON
matching and 10鈩?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 12-pin QFN (3mm x 3mm) package and a 10-pin
碌MAX package.
