DG411AK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411AK is a precision monolithic quad single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It features four independent switches with an on-resistance of 25 ohms and a turn-on time of 110 nanoseconds. The device supports a maximum supply voltage of 44 volts and operates within a temperature range of -55°C to +125°C. It utilizes a high-voltage silicon-gate process with an epitaxial layer to prevent latch-up, ensuring reliable performance in demanding environments.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'AK' corresponds to the 16-pin CerDIP package and the extended -55°C to +125°C operating temperature range. Confirm RoHS compliance status as older manufacturing runs may differ from current specifications. Ensure the source document matches the exact part number to validate electrical parameters against the datasheet.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG411AK when wide dynamic range and low signal distortion are required. This component is appropriate for portable and battery-powered systems due to its ultra-low power characteristics. Consider the CerDIP package for applications requiring operation at elevated temperatures up to 125°C.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG411AK belongs to the DG411/412/413 series of precision monolithic quad SPST CMOS analog switches. These devices are designed to provide high-speed, low-error switching of precision analog signals. The AK suffix specifically denotes the ceramic dual-in-line package variant optimized for extended temperature ranges.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG411DJ serves as a plastic DIP alternative with a standard -40°C to +85°C temperature range. The DG411DY offers a narrow SOIC surface-mount option. Verify pinout compatibility and thermal dissipation requirements when substituting these variants.
