Vishay Siliconix

DG308A, DG309

TYPICAL CHARACTERISTICS (25 °C, unless otherwise noted)

APPLICATIONS

Single Supply Operation

The DG308A and DG309 will switch positive analog signals

while using a single positive supply. This will allow use in

many applications where only one supply is available. The

trade-offs or performance given up while using single

supplies are:

stated in the absolute maximum ratings section of the data

sheet, the analog voltage should not go above or below the

supply voltages which in single supply operation are V+ and

0 V.

Vishay Siliconix maintains worldwide manufacturing capability. Products may be manufactured at one of several qualified locations. Reliability data for Silicon

Technology and Package Reliability represent a composite of all qualified locations. For related documents such as package/tape drawings, part marking, and
