Overview
The DG418CY+ 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 flatness of 4Ω max over the signal range. It offers turn-on time ≤175ns, turn-off time ≤145ns, and charge injection ≤10pC. Operating temperature range is 0°C to +70°C. Package: 8-SO.
Feature Summary
- Guaranteed low on-resistance matching and flatness for improved signal integrity
- Low power consumption with minimal leakage current across temperature ranges
- High electrostatic discharge tolerance exceeding 2000V per Method 3015.7
- Compatible with TTL and CMOS logic levels for flexible interface integration
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 RoHS compliance status and lot traceability upon receipt. Ensure proper ESD handling protocols during storage and assembly. Check datasheet revisions for any updates to electrical characteristics or pin configurations before finalizing procurement orders.
Selection Notes
Select this component when precise analog switching with low distortion is required in single-channel applications. Consider the 8-SO package for surface-mount designs needing compact footprints. Evaluate supply voltage compatibility against system requirements, as performance varies between single and dual supply modes. Verify thermal dissipation limits within the specified operating temperature range.
Part Context
The DG418CY+ belongs to the DG417/DG418/DG419 family of improved precision CMOS analog switches. It shares design enhancements like reduced charge injection and better on-resistance matching with its siblings. While the DG417 is normally closed and DG419 is SPDT, the DG418 specifically provides a normally open SPST configuration. This family targets high-performance data acquisition and signal routing systems.
