DG211DY+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG211DY+ is a monolithic quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on dual power supplies ranging from ±4.5V to ±18V and features a maximum drain-source ON-resistance of 175 Ohms. The device guarantees a maximum turn-on time of 1000ns and a maximum turn-off time of 500ns. It is housed in a 16-pin SOIC package with an operating temperature range of -40°C to +85°C. The component draws a maximum supply current of 400uA and supports a continuous DC switch current of 20mA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'DY+' corresponds to the narrow SOIC package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status through official documentation. Ensure the ordering code matches the exact pinout and electrical specifications required for the design. Cross-reference the datasheet revision date to validate parameter accuracy.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring guaranteed break-before-make timing and robust latch-up protection during fault conditions. The DG211DY+ is suitable for portable systems due to its low power consumption compared to legacy CMOS switches. Consider the 175 Ohm ON-resistance limit when designing signal paths sensitive to voltage drop or power dissipation.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG211 series serves as a direct replacement for older discrete analog switch solutions. It integrates four independent SPST switches into a single monolithic CMOS die. The device simplifies system design by removing the need for external level-shifting supplies typically required by earlier generations of similar components.

Analog Switches, Multiplexers, Demultiplexers FAQ

Does the DG211 require a separate VL supply?

No, Maxim's DG211 eliminates the need for the third VL power supply that was required for the original manufacturer's DG211.

What is the maximum analog signal range?

The analog signal range is -15V to +15V when operated with ±15V power supplies.

How does the device handle fault conditions?

The switches are guaranteed not to latch up if power supplies are disconnected while input signals remain connected.
