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:

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.
