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 channels and on-resistance flatness of 4 Ω maximum over the signal range. 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. It offers rail-to-rail signal handling and TTL/CMOS logic compatibility.

Feature Summary

Guaranteed on-resistance matching and flatness for improved signal integrity
Low charge injection and ultralow power consumption
TTL and CMOS logic compatible input levels
High electrostatic discharge tolerance

Applications

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

Procurement Notes

Verify the specific suffix 'CJ' corresponds to the 8-pin Plastic DIP package and the commercial temperature range of 0°C to +70°C. Confirm that the component is sourced from authorized distributors to ensure authenticity, as counterfeit parts may not meet the guaranteed on-resistance matching specifications. Check RoHS compliance status if required for your assembly process.

Selection Notes

Select the DG419CJ when a single SPDT configuration with guaranteed channel matching is required. Ensure the application voltage stays within the +10V to +30V single supply or ±4.5V to ±20V dual supply limits. Consider the 35 Ω maximum on-resistance and 175 ns switching times against system bandwidth and latency requirements. Verify that the 8-pin PDIP footprint fits the PCB layout constraints.

Part Context

The DG419CJ belongs to the DG417/DG418/DG419 family of precision analog switches. While the DG417 is SPST normally closed and the DG418 is SPST normally open, the DG419 provides an SPDT configuration with one normally closed and one normally open switch. This family utilizes an LC2MOS process designed for low power and fast switching in precision instrumentation applications.
