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 60. 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.

__________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 rDS(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.
