DG411CY+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411CY+ is a quad, single-pole/single-throw (SPST) 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 45Ω and an on-resistance match between channels of 3Ω max. Turn-on time is 175ns max, while turn-off time is 145ns max. Charge injection is limited to 10pC max. The component is housed in a 16-pin Narrow SO package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix 'CY' corresponds specifically to the 16-pin Narrow SOIC package and the commercial temperature range of 0°C to +70°C. Confirm that the manufacturer designation matches Analog Devices Inc. or Maxim Integrated as indicated in official documentation. Ensure compliance with RoHS standards before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed SPST configuration is required for analog signal routing. The narrow SOIC package is suitable for surface-mount applications requiring compact footprints. Verify that the supply voltage requirements align with the specified single or bipolar ranges to ensure proper operation within the absolute maximum ratings.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG411 series represents an improved redesign of industry-standard analog switches. It serves as a drop-in replacement for older DG211/DG212 devices, offering lower on-resistance and faster switching times. The DG411 variant specifically provides a normally closed switch configuration, distinguishing it from the normally open DG412 and mixed DG413 variants.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitute part numbers include DG411DJ, DG411EUE, and DG411CJ. These alternatives share the same functional specifications but differ in package type or operating temperature range.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic state for the DG411 switch?

The DG411 is a normally closed (NC) switch. A logic '0' input turns the switch ON, while a logic '1' input turns the switch OFF.

How does the DG411 compare to the DG211?

The DG411 offers lower analog on-resistance (35Ω max vs. higher values in older generations) and faster switch times compared to the DG211. It also features reduced charge injection and latch-up protection.

What is the maximum analog signal range?

The device supports a maximum analog signal range of ±15V when operated with ±15V supplies. The total power supply difference must not exceed 44V.
