Vishay Siliconix
Low Voltage, Dual Supply, Low RON, Quad SPST Analog Switches
DESCRIPTION
FEATURES
The DG9424, DG9425, DG9426 are low voltage precision
monolithic quad single-pole-single-throw analog switches.
• 2.7 V thru 12 V single supply or ± 3 thru ± 6 dual supply
Using BiCMOS wafer fabrication technology allows the
DG9424, DG9425, DG9426 to operate on single and dual
supplies. Single supply voltage ranges from 3 V to 12 V while
dual supply operation is recommended with ± 3 V to ± 6 V.
• Fast switching - tON: 42 ns
- tOFF: 28 ns
Combining high speed (tON: 42 ns), flat RDS(on) over
the analog signal range (), minimal insertion lose (-3 dB at
190 MHz), and excellent crosstalk and off-isolation
performance, the DG9424, DG9425, DG9426 are ideally
suited for audio and video signal switching.
The DG9424 and DG9425 respond to opposite control logic
as shown in the truth table. The DG9426 has two normally
open and two normally closed switches.
• On-resistance - RDS(on): 1.7
• TTL, CMOS compatible
• Low leakage: 0.2 nA
• 2000 V ESD protection
BENEFITS
• Widest dynamic range
• Low signal errors and distortion
• Break-before-make switching action
• Simple interfacing
APPLICATIONS
• Automatic test equipment
• Data acquisition systems
• Communication systems
• ADC systems
• xDSL and PBX / PABX
• Audio signal routing
