DG419CY+

Overview

The DG419CY+ is a single-channel SPDT analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. The device features a maximum on-resistance of 35Ω, with guaranteed on-resistance matching of 3Ω and flatness of 4Ω over the signal range. Switching times are less than 175ns for turn-on and 145ns for turn-off. It offers low charge injection (10pC max) and off-leakage current (<5nA at +85°C). The component is housed in an 8-pin SOIC package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

Guaranteed on-resistance matching between channels and flatness over the signal range
Low power consumption with rail-to-rail signal handling capabilities
TTL/CMOS-logic compatible inputs for flexible control integration

Applications

Sample-and-Hold Circuits
Communications Systems
Test Equipment

Procurement Notes

Verify the specific suffix 'CY' against official documentation to confirm the 0°C to +70°C industrial temperature rating and SOIC package type. Ensure that the ordering information matches the exact manufacturer part number to avoid discrepancies in electrical characteristics or physical dimensions.

Selection Notes

Select this component when a single-pole double-throw configuration is required with guaranteed channel matching. It is suitable for applications needing TTL/CMOS logic compatibility and operation within standard industrial temperature ranges. Verify that the bipolar or single-supply voltage requirements align with the specified operational limits.

Part Context

This component belongs to the redesigned DG417/DG418/DG419 series of precision CMOS monolithic analog switches. The DG419 variant specifically provides a single-pole double-throw configuration, distinguishing it from the single-pole single-throw DG417 and DG418 models within the same family.
