Overview
The DG419LEUA+ is a precision CMOS analog switch featuring single-pole/double-throw (SPDT) configuration in an 8-pin µMAX package. It operates with dual supplies from ±4.5V to ±20V or a single supply of +9V to +36V. Key electrical parameters include a maximum on-resistance of 35Ω, guaranteed matching between channels of 3Ω max, and flatness of 4Ω max. The device supports rail-to-rail signal handling, low charge injection of 15pC, and off-leakage current under 5nA at +85°C. Switching times are less than 175ns for turn-on and 185ns for turn-off.
Feature Summary
- +3V logic-compatible digital inputs ensure compatibility with TTL and CMOS logic levels.
- Rail-to-rail analog signal handling capability allows operation across the full supply range.
- Power-supply sequencing-free operation eliminates latch-up risks during power-up.
Applications
- Sample-and-Hold Circuits
- Precision Test Equipment
- Battery-Operated Systems
Procurement Notes
Verify the ordering suffix LEUA corresponds to the 8-pin µMAX package variant when sourcing. Confirm that the component meets RoHS compliance standards as indicated by the plus sign in the part number. Ensure the supplier provides documentation verifying the extended temperature rating of -40°C to +85°C. Cross-reference the manufacturer's latest datasheet for any potential pinout or specification updates before finalizing procurement orders.
Selection Notes
Select this component for applications requiring SPDT switching with tight resistance matching. The +3V logic compatibility simplifies interface design with low-voltage microcontrollers. Consider the µMAX package size constraints against thermal dissipation requirements. Verify that the 35Ω on-resistance meets the signal integrity needs of the specific circuit application.
Part Context
This device belongs to the DG417L/DG418L/DG419L family of precision analog switches manufactured by Analog Devices/Maxim Integrated. It serves as a plug-in upgrade for industry-standard DG417/DG418/DG419 devices. The L-series designation indicates enhanced features such as +3V logic compatibility and power-supply sequencing-free operation compared to older generations.
Replacement Considerations
Public confirmed substitute part numbers include DG419LDJ+ and DG419LDY+. These variants offer identical electrical specifications but differ in package type, utilizing Plastic DIP and SOIC respectively instead of the µMAX package found in the DG419LEUA+.
