DG308A, DG309 Datasheet

DG308A, DG309
Vishay Siliconix
Quad Monolithic SPST CMOS Analog Switches
DESCRIPTION
FEATURES
Featuring low on-resistance (60 ) and fast switching
(130 ns), the DG308A is supplied in the “normally open”
configuration while DG309 is supplied “normally closed”.
Input thresholds are high voltage CMOS compatible.
• ± 15 V analog input range
Designed with the Vishay Siliconix PLUS-40 CMOS process
to combine low power dissipation with a high breakdown
voltage rating of 44 V, each switch conducts equally well in
both directions when on, and blocks up to the supply voltage
when off. An epitaxial layer prevents latch up.
• CMOS logic compatible
• Low on-resistance: 60 
• Fast switching: 130 ns
• Low power dissipation: 30 nW
BENEFITS
• Full rail-to-rail analog signal range
• Low signal error
The DG308B, DG309B upgrades are recommended for new
designs.
• Wide dynamic range
• Single or dual supply capability
• Static protected logic inputs
• Space savings (TSSOP)
APPLICATIONS
• Portable and battery powered instrumentation
• Communication systems
• Computer peripherals
• High-speed multiplexing

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
