High Voltage Single SPDT Analog Switch in SOT23-8
DESCRIPTION
The DG449 is a dual supply single-pole/double-throw
(SPDT) switches. On resistance is 38 and flatness is 2.6
max over the specified analog signal range. These analog
switches were designed to provide high speed, low error
switching of precision analog signals. The primary
application areas are in the routing and switching in
telecommunications and test equipment. Combining low
power, low leakages, low on-resistance and small physical
size, the DG449 is also ideally suited for portable and battery
powered industrial and military equipment.
The DG449 operates either from a single + 7 V to 36 V
supply or from dual ± 4.5 V to ± 20 V supplies. It is offered in
the very popular, small SOT23-8 package.
FEATURES
• ± 15 V analog signal range
• On-resistance - RDS(on): 38 max.
• VL logic supply not required
• TTL CMOS input compatible
• Rail to rail signal handling
• Dual or single supply operation
BENEFITS
• Wide dynamic range
• Low signal errors and distortion
• Break-before-make switching action
• Simple interfacing
• Small SOT23-8ld package; reduced board space
• Improved reliability
APPLICATIONS
• Precision test equipment
• Precision instrumentation
• Communications systems
• PBX, PABX systems
• Audio equipment
• Redundant systems
• PC multimedia boards
• Hard disc drives
