DG417DK

Overview

The DG417DK is a single-pole/single-throw (SPST) precision CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within an extended industrial temperature range of -55°C to +125°C and utilizes an 8-pin CERDIP package. The device supports single-supply voltages from +10V to +30V or bipolar supplies from ±4.5V to ±20V. Key electrical specifications include a maximum on-resistance of 35Ω, guaranteed on-resistance matching of 3Ω max, and on-resistance flatness of 4Ω max. Switching times are limited to 175ns for turn-on and 145ns for turn-off, with charge injection capped at 10pC.

Feature Summary

Guaranteed low on-resistance matching between channels for improved signal integrity
Extended operating temperature range suitable for harsh industrial environments
Low power consumption with minimal supply current requirements
High electrostatic discharge tolerance ensuring robust device reliability

Applications

Sample-and-Hold Circuits
Test Equipment
Guidance and Control Systems

Procurement Notes

Verify the specific ordering suffix DK against official manufacturer documentation to confirm the ceramic DIP package and extended temperature rating. Ensure compatibility with existing PCB footprints designed for 8-pin CERDIP components. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement decisions.

Selection Notes

Select this component when precise channel-to-channel resistance matching is critical for the application. The extended temperature range makes it suitable for demanding industrial or military environments where standard commercial grade parts may fail. Verify that the logic voltage levels align with the system's control signals to ensure proper switching operation.

Part Context

This component belongs to the DG417/DG418/DG419 family of improved SPST/SPDT analog switches. The DG417 variant specifically provides a normally closed configuration. The 'DK' suffix denotes the ceramic dual in-line package and the wide industrial temperature range, distinguishing it from plastic DIP or SOIC variants.
