MAX4695 Datasheet, PDF (1/11 Pages) Maxim Integrated Products – Low-Voltage, 60ohm Dual SPDT Analog Switch in Thin QFN

19-2044; Rev 1, 2/05
Low-Voltage, 60Ω Dual
SPDT Analog Switch in Thin 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
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.
