__________Applic ations Information
Operation with S upply V oltages
Other than ±5V
Using supply voltages less than ±5V reduces the analog
signal range. The MAX4518/MAX4519 muxes operate
with ±2.7V to ±8V bipolar supplies or with a +2.7V to
+15V single supply. Connect V- to GND when operating
with a single supply. Both device types can also operate
with unbalanced supplies, such as +10V and -5V. The
Typical Operating Characteristics graphs show typical
on-resistance with ±3V, ±5V, +3V and +5V supplies.
(Switching times increase by a factor of two or more for
operation at 5V.)
Overvoltage Protec tion
Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maxi-
mum ratings, because stresses beyond the listed rat-
ings can cause permanent damage to the devices.
Always sequence V+ on first, then V-, followed by the
logic inputs, NO, or COM. If power-supply sequencing
is not possible, add two small signal diodes (D1, D2) in
series with supply pins for 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
operation is unchanged, and the difference between
V+ and V- should not exceed 17V. These protection
diodes are not recommended when using a single supply.
