DG418LDJ

Overview

The DG418LDJ is a single-channel, SPST-NO analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates with a single supply voltage ranging from 10V to 30V or dual supplies of ±4.5V to ±20V. The device features a maximum on-resistance of 35 ohms and low charge injection of 3pC. Switching times are specified at a maximum of 175ns for turn-on and 145ns for turn-off. It is housed in an 8-PDIP package with a lead pitch of 0.300 inches (7.62mm) and supports through-hole mounting.

Feature Summary

Single-pole single-throw normally open configuration for signal routing
Low charge injection characteristics suitable for precision applications
Rail-to-rail switching capability across wide supply voltage ranges

Applications

Data acquisition systems requiring precise signal isolation
Programmable gain amplifiers and attenuators
Sample-and-hold circuits in instrumentation

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance requirements as the specific suffix may indicate legacy manufacturing standards. Check for alternative surface-mount packages if PCB layout constraints require modern assembly methods. Validate thermal performance within the specified operating temperature range during integration.

Selection Notes

Select this component when a single analog switch with low on-resistance is required for high-voltage single-supply operation. Consider the 8-PDIP package for prototyping or through-hole designs. Evaluate the 35-ohm on-resistance against load requirements to ensure minimal signal attenuation. Compare switching speeds against system timing constraints before finalizing the design.

Part Context

This part belongs to the DG417-DG419 family of improved CMOS analog switches. These devices offer enhanced performance over earlier generations with lower power consumption and faster switching speeds. The family provides various configurations including SPST and SPDT options to support diverse signal switching needs in industrial and consumer electronics.
