DG419CJ+

Overview

The DG419CJ+ 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 switches 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 parameters 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 with an operating temperature range of 0°C to +70°C.

Feature Summary

Guaranteed on-resistance matching of 3 Ω maximum between channels for improved signal integrity.
Low off-leakage current performance, specified at less than 5nA at +85°C.
High electrostatic discharge tolerance of 2000V minimum per Method 3015.7.
TTL/CMOS logic compatible input interface for versatile digital control.

Applications

Sample-and-Hold Circuits
Precision Test Equipment
Battery-Operated Systems

Procurement Notes

Verify the specific suffix 'CJ+' corresponds to the required 0°C to +70°C industrial temperature grade and 8-pin PDIP package configuration. Confirm that the ordering information matches the manufacturer's current datasheet revision to ensure compatibility with design specifications. Cross-reference the part number against official distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when precise channel-to-channel resistance matching is critical for differential signal routing. The guaranteed 3 Ω match and 4 Ω flatness make it suitable for high-accuracy instrumentation applications. Ensure the system operates within the specified +10V to +30V single supply or ±4.5V to ±20V dual supply ranges to maintain optimal switching performance and leakage characteristics.

Part Context

The DG419CJ+ belongs to the redesigned DG417/DG418/DG419 family of precision CMOS analog switches. Unlike standard versions, these improved devices offer guaranteed on-resistance matching and flatness. The DG419 variant specifically provides SPDT functionality with one normally closed and one normally open switch, distinguishing it from the SPST configurations of the DG417 and DG418 models.
