DG419DY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG419DY 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 operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. Key electrical parameters include a maximum on-resistance of 35Ω, guaranteed on-resistance matching of 3Ω max between switches, and on-resistance flatness of 4Ω max over the signal range. Switching times are less than 175ns for turn-on and 145ns for turn-off. It offers rail-to-rail signal handling, TTL/CMOS logic compatibility, and an ESD tolerance of 2000V minimum per Method 3015.7.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature range. Ensure that any alternative part numbers selected maintain identical pin configurations and electrical specifications to guarantee functional compatibility within the target circuit design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when precise analog signal routing with minimal resistance variation is required. The SPDT configuration allows for selecting between two input sources. Verify that the system supply voltage falls within the specified single or bipolar ranges to ensure proper operation and signal integrity across the full operating temperature spectrum.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG419 belongs to the DG417/DG418/DG419 family of improved precision analog switches. While the DG417 is normally closed SPST and the DG418 is normally open SPST, the DG419 provides SPDT functionality with one normally closed and one normally open switch. This family utilizes an enhanced LC2MOS process for optimized performance characteristics.
