MAX4677 Datasheet, PDF (1/12 Pages) Maxim Integrated Products – 2Ω, Quad, SPST, CMOS Analog Switches

19-1713; Rev 0; 4/00
2Ω, Quad, SPST, CMOS Analog Switches
General Description
The MAX4677/MAX4678/MAX4679 quad analog switch-
es feature 1.6Ω max on-resistance (R_ON) when operat-
ing from a dual ±5V supply. R_ON is matched between
channels to 0.3Ω max and is flat (0.4Ω max) over the
specified signal range. Each switch can handle Rail-to-
Rail^® analog signals. Off-leakage current is 0.1nA at
+25°C. These switches are ideal in low-distortion appli-
cations and are the preferred solution over mechanical
relays in automated test equipment. They have low
power requirements, require less board space, and are
more reliable than mechanical relays.
The MAX4677 has four normally closed (NC) switches,
and the MAX4678 has four normally open (NO) switch-
es. The MAX4679 has two NC and two NO switches
and features guaranteed break-before-make switching.
The MAX4677/MAX4678/MAX4679 operate from either
a single +2.7V to +11V or dual ±2.7V to ±5.5V supplies,
making them ideal for use in digital card applications
and single-ended 75Ω systems.
These devices feature a separate logic supply input
that operates from +2.7V to V+, allowing independent
logic and analog supplies.
