Applications Information
Operation with Supply Voltages
Other Than ±15V
Using supply voltages other than ±15V reduces the
analog signal range. The DG441/DG442 switches oper-
ate with ±4.5V to ±20V bipolar supplies or with a +10V
to +30V single supply; connect V- to 0V when operating
with a single supply. Also, all 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 sup-
plies. (Switching times increase by a factor of two or
more for operation at ±5V.)
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 rat-
ings can cause permanent damage to the devices.
Always sequence V+ on first, followed by V- and logic
inputs. If power-supply sequencing is not possible, add
two small, external signal diodes in series with supply
pins for overvoltage protection (Figure 1). Adding exter-
nal diodes reduces the analog-signal range to 1V
below V+ and 1V above 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.
