Low Power, High Voltage SPST Analog Switches
DESCRIPTION
FEATURES
The DG447 and DG448 are dual supply single-pole/single-

•
throw (SPST) switches. On resistance is 25 Ω maximum and
flatness is 2.2 Ω max over the specified analog signal range.
These analog switches were designed to provide high
speed, low error switching of precision analog signals. The
primary application areas are in the routing and switching in
± 15 V Analog Signal Range

battery powered industrial and military equipment.
The DG477 has one normally closed switch, while the
DG448 switch is normally open. They operate either from a
single + 7 V to 36 V supply or from dual ± 4.5 V to ± 20 V
supplies. They are offered in the very popular, small
T6SOP6 package.

Notes:
a. Refer to PROCESS OPTION FLOWCHART.
b. Room = 25 °C, Full = as determined by the operating temperature suffix.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
d. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
e. Guaranteed by design, not subject to production test.
f. VIN = input voltage to perform proper function.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
