Overview
The DG419BAK is a precision CMOS analog switch manufactured by Vishay Siliconix, housed in a 16-pin CDIP package. It features a single SPDT configuration with a maximum on-resistance of 85 ohms and a supply voltage range up to 44V. The device supports dual supplies from ±15V to ±20V or single supplies up to 36V. Operating temperatures span from -55°C to +125°C, ensuring reliability in harsh environments. Key electrical parameters include a switching time of 200ns max and leakage current under 250pA.
Feature Summary
- High-precision CMOS technology for low distortion
- Wide operating temperature range for industrial use
- Break-before-make switching action prevents signal glitches
Applications
- Precision test equipment signal routing
- Industrial instrumentation data acquisition
- Harsh environment sensor interfacing
Procurement Notes
Verify the specific suffix 'BAK' against official Vishay documentation to confirm the ceramic DIP package and commercial/industrial grade specifications. Ensure compatibility with existing PCB footprints for 16-pin CDIP components during procurement planning.
Selection Notes
Select this component when high thermal stability and wide voltage operation are required. Compare on-resistance values against system requirements if lower resistance is needed, as other variants in the series offer different performance levels.
Part Context
Part of the DG419 family of precision analog switches. This series is known for LC2MOS process technology, offering a balance of speed, power dissipation, and signal integrity for general-purpose analog switching applications.
Replacement Considerations
Check for direct pin-compatible alternatives such as ADG419 or Maxim Integrated equivalents. Verify that substitute parts meet the same voltage and temperature ratings before implementation.
