FUNCTION
FUNCTION
FUNCTION
The DG401/DG403/DG405 switches operate with
±4.5V to ±20V bipolar supplies or with a +10V to +30V
single supply. In either case, analog signals ranging
from V+ to V- can be switched. The Typical Operating
Characteristics graphs illustrate typical analog-signal
and supply-voltage on-resistance variations. The usual
on-resistance temperature coefficient is 0.5%/°C (typ).
These devices operate with a single positive supply or
with bipolar supplies. They maintain TTL compatibility
with supplies anywhere in the ±4.5V to ±20V range as
long as V
supply at voltages other than +5V, the devices will
operate at CMOS-logic-level inputs.
Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute
maximum ratings because stresses beyond the listed
ratings may cause permanent damage to the devices.
Always sequence V+ on first, followed by V
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 diodes reduces the analog-signal
range to 1V below V+ and 1V below V-, without affect-
ing low switch resistance and low leakage
characteristics. Device operation is unchanged, and
the difference between V+ and V- should not exceed
+44V.
