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 guaranteed on-resistance matching of 3 Ω maximum and on-resistance flatness over the signal range of 4 Ω maximum. 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 35 Ω, charge injection of 10 pC maximum, and off-leakage current less than 5 nA at +85°C. Switching times are specified as 175 ns maximum for turn-on and 145 ns maximum for turn-off. It is housed in an 8-SOIC package with an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'DY+' corresponds to the 8-SOIC surface-mount package and the industrial temperature range (-40°C to +85°C). Confirm that the ordering information matches the manufacturer's current datasheet revision, as legacy Maxim Integrated products may have transitioned specifications under Analog Devices Inc. Ensure compatibility with the required voltage levels and pin configurations before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG419DY+ when a single-pole/double-throw configuration is required with tight on-resistance matching constraints. This component is suitable for applications demanding low charge injection and high ESD protection. Consider the SOIC package size and the specific bipolar or single-supply voltage requirements. Verify that the switching speed and leakage current specifications meet the system's precision requirements compared to standard SPST alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG419DY+ belongs to the redesigned DG417/DG418/DG419 series of precision CMOS analog switches. Unlike previous iterations, this version guarantees improved channel matching and flatness. It serves as a plug-in upgrade for industry-standard switches while offering enhanced performance metrics such as lower charge injection and better off-leakage characteristics across the extended temperature range.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG419DJ+ is the direct through-hole PDIP-8 replacement for the DG419DY+ within the same family, sharing identical electrical specifications and functionality but differing only in the physical package type.
