__________Applic ations Information
Operation with S upply V oltages
Other than ±15V
Using supply voltages other than ±15V reduces the
analog signal range. The DG406/DG407 switches oper-
ate with ±4.5V to ±20V bipolar supplies or with a +4.5V
to +30V single supply; connect V- to GND when operat-
ing with a single supply. Also, both device types can
operate with unbalanced supplies such as +24V and
-5V. The Typical Operating Characteristics graphs
show typical on-resistance with 20V, 15V, 10V, 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 may cause permanent damage to the devices.
Always sequence V+ on first, then V-, followed by the
logic inputs and analog signals. If power-supply
sequencing is not possible, add two small signal
diodes in series with supply pins for overvoltage pro-
tection (Figure 1). Adding diodes reduces the analog
signal range to 1V above V+ and 1V below V-, but low
switch resistance and low leakage characteristics are
unaffected. Device operation is unchanged, and the
difference between V+ and V- should not exceed +44V.
