Quad, SPST Analog Switches
_______________General Description
The DG308A/DG309 are quad, single-pole-single-throw
(SPST) analog switches. The DG308A is normally open
(SPST, NO), while the DG309 is normally closed (SPST,
NC). Both parts feature fast switching speeds and low on-
resistance over the analog range. Other features include a
turn-on time under 120ns, a turn-off time under 90ns, and a
channel on-resistance of 60Ω. CMOS inputs provide
reduced input loading and very low leakage currents.
Both parts feature a 44V maximum breakdown voltage rat-
ing that allows 30V peak-to-peak switch-off blocking
capacity. The DG308A/DG309 can be used with split sup-
plies (±5V to ±20V) or a single positive supply (+5V to
+30V), while retaining CMOS-logic-compatible inputs.

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.

__________Applications Information
The DG308A/DG309 switch positive analog signals while
using a single positive supply, allowing use in applica-
tions where only one supply is available. The disadvan-
tages of using a single supply are slower switching
speed and increased r
DS(ON)
. The
Power-Supply
Current and Voltage vs. Temperature
graph shows the
typical curve for a single-supply design. As stated in the
Absolute Maximum Ratings, the analog voltage should
not go above or below the supply voltages, which are V+
and 0V in single-supply operation.
Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product. No circuit patent licenses are
implied. Maxim reserves the right to change the circuitry and specifications without notice at any time.
