Overview
The DG417CJ is a single-channel, single-pole/single-throw (SPST) precision analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within a temperature range of 0°C to +70°C and is housed in an 8-pin Plastic DIP package. The device supports single-supply voltages from +10V to +30V or dual supplies from ±4.5V to ±20V. Key electrical specifications include a maximum on-resistance of 35Ω, a maximum turn-on time of 175ns, and a maximum turn-off time of 145ns. It features guaranteed on-resistance matching of 3Ω and flatness of 4Ω over the signal range.
Feature Summary
- Guaranteed low charge injection for improved signal integrity
- TTL and CMOS logic compatible input interface
- Rail-to-rail signal handling capability
- High electrostatic discharge tolerance
Applications
- Sample-and-Hold Circuits
- Communications Systems
- Test Equipment
- Battery-Operated Systems
- Audio Signal Routing
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required package type and temperature rating. Ensure compliance with RoHS directives if applicable to the target assembly process. Review datasheet revisions for any updates to absolute maximum ratings before final integration.
Selection Notes
Select this component when a normally closed SPST configuration is required. Verify that the operating voltage range aligns with the system's power supply architecture. Consider the thermal dissipation limits if multiple units are utilized in close proximity. Ensure the logic input levels match the controlling microcontroller or digital interface signals.
Part Context
This part belongs to the DG417/DG418/DG419 family of improved precision CMOS analog switches. The DG417 variant specifically provides a normally closed switch configuration, distinguishing it from the normally open DG418 and the dual-switch DG419. All members share similar performance characteristics regarding speed and leakage current.
