Overview
The DG418AK-E3 is a precision single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It features a CMOS logic interface and operates within a supply voltage range of 15 V to 15 V for dual supplies, or 13 V to 44 V for single supplies. The device exhibits a maximum on-resistance of 35 Ohms and supports a DC switch current of 30 mA. Key timing parameters include a maximum turn-on time of 175 ns and a maximum turn-off time of 145 ns. It is housed in an 8-pin CDIP-8 package with a power dissipation rating of 600 mW. The component functions reliably across an extended temperature range from -55°C to +125°C.
Feature Summary
- Precision SPST configuration designed for high-fidelity signal routing applications
- Extended industrial temperature capability suitable for harsh environments
- Low quiescent current consumption for efficient power management
Applications
- High-precision data acquisition systems requiring low leakage
- Industrial process control instrumentation
- Medical equipment signal conditioning circuits
Procurement Notes
Verify the specific suffix E3 confirms RoHS compliance status prior to ordering. Confirm that the CDIP-8 through-hole package aligns with the target PCB footprint requirements. Ensure the manufacturer designation matches Vishay / Siliconix specifications to avoid counterfeit components during the sourcing phase.
Selection Notes
Select this component when a single channel with precise switching characteristics is required. The wide operating temperature range distinguishes it from commercial grade alternatives. Verify that the 35 Ohm on-resistance meets the signal integrity constraints of the application circuit design.
Part Context
This part belongs to the DG series of precision analog switches produced by Vishay / Siliconix. It represents a specialized variant optimized for through-hole mounting via the Minidip package style. The device serves as a robust solution for applications demanding reliable analog signal path control under varying environmental conditions.
Replacement Considerations
The DG418DJ-E3 offers identical electrical performance but utilizes a PDIP-8 package instead of CDIP-8. Designers must evaluate mechanical fit and thermal dissipation differences when considering cross-package substitution.
