Overview
The DG417CJ+ is a single-pole/single-throw (SPST) precision CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. The device features a maximum on-resistance of 35Ω, guaranteed on-resistance matching of 3Ω max, 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 low charge injection of 10pC max and off-leakage current below 5nA at +85°C. The component is housed in an 8-pin Plastic DIP package with an operating temperature range of 0°C to +70°C.

Procurement Notes
Verify the specific suffix 'CJ+' against official manufacturer documentation to confirm the exact plastic DIP package type and commercial temperature grade. Ensure compatibility with existing PCB footprints and verify that the component meets all required environmental standards for the intended application environment before finalizing procurement plans.
Selection Notes
Select this component when a normally closed SPST configuration is required within the DG417 series. Compare it against the DG418 for normally open applications or the DG419 for SPDT requirements. Consider the bipolar supply operation limits and ensure the thermal dissipation capabilities align with the expected ambient temperature conditions during continuous operation.
Part Context
This part belongs to the redesigned DG417/DG418/DG419 family of precision CMOS analog switches. These devices utilize a 44V silicon-gate process to achieve improved performance characteristics compared to previous generations. The family is designed to offer plug-in upgrades while maintaining industry-standard pinouts and form factors for legacy system integration.
