Overview
The DG417BAK is a precision monolithic CMOS single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It features a low on-resistance of 25 Ohms maximum and supports dual supply voltages ranging from -15 V to +15 V, with a total operating range of 30 V. The device operates within an extended industrial temperature range of -40°C to +85°C. Key electrical specifications include a maximum power dissipation of 400 mW, a maximum supply current of 1 µA, and a DC switch current capability of 30 mA. Transition times are specified at a maximum of 89 ns for turn-on and 80 ns for turn-off. The component is housed in an 8-pin DIP package.
Feature Summary
- Precision monolithic CMOS construction ensures stable switching performance
- Supports wide dual supply voltage operation up to ±15 V
- Low quiescent supply current minimizes power consumption
Applications
- Data acquisition systems requiring precise signal routing
- Instrumentation circuits needing high isolation
- Process control applications with extended temperature requirements
Procurement Notes
Verify the specific suffix and manufacturer designation when sourcing this component, as availability may vary between original Siliconix and current Vishay Semiconductors production lines. Confirm RoHS compliance status through official datasheets or distributor documentation, as legacy parts often have specific environmental declarations. Ensure the package type matches the intended PCB footprint before ordering.
Selection Notes
Select this part for applications requiring a single SPST channel with moderate speed and low leakage. Compare against the DG417LDY variant if lower on-resistance is required, noting that the LDY version typically offers improved resistance characteristics. Verify that the 25 Ohm on-resistance meets the signal integrity requirements of the target circuit design.
Part Context
This component belongs to the DG41x series of precision analog switches from Vishay Siliconix. The series includes variants such as the DG417BDY and DG417LDY, which share similar functional architectures but differ in package styles and specific electrical parameters like on-resistance. The BAK suffix specifically denotes the 8-pin DIP package configuration.
Replacement Considerations
Publicly documented direct replacements include the DG417BDJ-E3 for through-hole DIP applications and the DG417LDQ-T1 for surface-mount MSOP-8 packages. Verify pin compatibility and parameter tolerances before substituting.
