General Description

The MAX4677/MAX4678/MAX4679 quad analog switch-

es feature 1.6Ωmax on-resistance (RON) when operat-

ing from a dual ±5V supply. RON is matched between

channels to 0.3Ωmax and is flat (0.4Ωmax) 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 75Ωsystems.

These devices feature a separate logic supply input

that operates from +2.7V to V+, allowing independent

logic and analog supplies.

___________Applications Information

Overvoltage Protection

Proper power-supply sequencing is recommended for

all CMOS devices. Do not exceed the absolute maxi-

mum ratings because stresses beyond the listed ratings

can cause permanent damage to the devices. Always

sequence V+ on first, then V-, then VLfollowed by the

logic inputs, NO_, NC_, or COM. If proper power-supply

sequencing is not possible, add two small signal diodes

(D1, D2) in series with the supply pins, and a Schottky

diode between V+ and VLfor overvoltage protection

(Figure 1). Adding diodes reduces the analog signal

range to one diode drop below V+ and one diode drop

above V-, but does not affect the devices’ low switch

resistance and low leakage characteristics. Device oper-

ation is unchanged, and the difference between V+ and

V- should not exceed 11V.

Power-supply bypassing improves noise margin and

prevents switching noise from propagating from the V+

supply to other components. A 0.1µF capacitor connect-

ed from V+ to GND is adequate for most applications.
