DG419DJ

Overview

The DG419DJ is a precision, monolithic CMOS single-pole/double-throw (SPDT) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features an enhanced LC2MOS process providing low power dissipation and high switching speed. The device guarantees on-resistance matching of 3 Ω maximum between channels and on-resistance flatness over the signal range of 4 Ω maximum. It operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. Key electrical characteristics include a maximum on-resistance of 35 Ω, turn-on time of 175 ns, turn-off time of 145 ns, and charge injection of 10 pC maximum. The component is housed in an 8-pin Plastic DIP package and supports an operating temperature range of -40°C to +85°C.

Feature Summary

Guaranteed on-resistance matching of 3 Ω maximum between switches
Low off-leakage current performance with less than 5nA at +85°C
High electrostatic discharge tolerance of 2000V minimum per Method 3015.7
TTL/CMOS logic compatible for flexible interface integration

Applications

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

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and temperature rating. Ensure that any alternative part numbers are cross-referenced with the original datasheet to validate pin compatibility and functional equivalence before procurement.

Selection Notes

Select this component when precise channel-to-channel resistance matching is required for differential signal paths. The guaranteed on-resistance flatness ensures consistent signal attenuation across the entire analog voltage range. Verify that the bipolar or single-supply voltage requirements align with the system's available power rails.

Part Context

The DG419DJ belongs to the redesigned DG417/DG418/DG419 series of precision analog switches. This family utilizes an improved LC2MOS silicon-gate process to deliver enhanced performance metrics compared to legacy versions. The DG419 specifically provides SPDT functionality, distinguishing it from the SPST configurations of the DG417 and DG418 within the same product line.
