DG417DY+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG417DY+ 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. 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 SOIC package with an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'DY+' against official manufacturer documentation to confirm the surface-mount SOIC package and extended industrial temperature range (-40°C to +85°C). Ensure compatibility with single or dual supply configurations as specified in the electrical characteristics table before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when precise on-resistance matching and low charge injection are required for signal routing applications. Verify that the 35Ω maximum on-resistance meets system requirements. Confirm that the 8-pin SOIC package dimensions fit the PCB layout constraints and that the logic input levels align with the control circuitry voltage standards.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG417DY+ belongs to the DG417/DG418/DG419 series of improved precision CMOS analog switches. This family replaces older industry-standard designs with enhanced performance metrics including lower leakage and better resistance matching. The DG417 variant specifically provides a normally closed SPST configuration within this optimized monolithic architecture.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the DG418DY+ (normally open) and DG419DY+ (SPDT). For legacy upgrades, verify that the improved electrical characteristics such as reduced charge injection and leakage currents are acceptable for the existing application design.
