FUNCTION

NAME

__________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

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.
