__________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.
