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:
1) increased RDS(on) and 2) slower switching speed. As
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
