DG418DJ

Overview

The DG418DJ is a single-pole/single-throw (SPST) precision CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. The device features a maximum on-resistance of 35Ω, guaranteed on-resistance matching of 3Ω, and on-resistance flatness of 4Ω. Turn-on time is 175ns maximum, while turn-off time is 145ns maximum. Charge injection is limited to 10pC. It supports rail-to-rail signal handling and is compatible with TTL/CMOS logic levels. The component is housed in an 8-pin Plastic DIP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

Guaranteed low charge injection for high-fidelity signal switching
TTL and CMOS logic level compatibility for versatile control integration
Rail-to-rail signal handling capability across the full supply voltage range

Applications

Sample-and-Hold Circuits
Communications Systems
Test Equipment
Battery-Operated Systems
Audio Signal Routing

Procurement Notes

Verify the specific suffix 'DJ' confirms the -40°C to +85°C industrial temperature rating and 8-PDIP package configuration. Confirm RoHS compliance status as indicated by the '+' designation if required by project specifications. Ensure the source documentation matches the manufacturer's official datasheet for accurate electrical parameter validation before finalizing procurement decisions.

Selection Notes

Select this component when a normally open SPST configuration is required with precise on-resistance matching. It is suitable for applications demanding low power consumption and high ESD tolerance. Consider alternative packages like SOIC if surface-mount technology is preferred over through-hole mounting. Verify that the operating voltage range aligns with the system's single or dual supply architecture.

Part Context

The DG418DJ belongs to the redesigned DG417/DG418/DG419 family of precision CMOS monolithic analog switches. This series improves upon previous generations by offering guaranteed on-resistance matching and flatness. The DG418 specifically provides a normally open switch configuration, distinguishing it from the normally closed DG417 and the double-throw DG419 within the same functional family.
