DG441AK-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG441AK-E3 is a CMOS analog switch IC from the Vishay Siliconix DG441 series, featuring four independent single-pole single-throw (SPST) channels. It utilizes a 16-pin Ceramic Dual In-Line Package (CDIP). The device supports dual supply voltages of ±15V and a single supply voltage of 12V. Key electrical parameters include a maximum on-resistance of 85 Ohms with a channel-to-channel matching of 4 Ohms maximum. Switching times are specified at 250ns for turn-on and 120ns for turn-off. The component operates within a temperature range of -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Four independent SPST analog switching channels integrated into a single unit
• High thermal stability suitable for extended industrial temperature ranges
• Low charge injection characteristics for signal integrity preservation

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring multi-channel signal routing
• Industrial process control instrumentation
• Test and measurement equipment signal paths

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify RoHS compliance status carefully as historical records indicate non-compliance for the base DG441AK variant. Confirm package authenticity as the ceramic CDIP form factor is distinct from standard plastic packages. Check manufacturer documentation for specific EOL or PCN notices affecting this legacy part number before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high-temperature operation up to 125°C is required alongside robust ceramic packaging. Ensure the design accommodates the 85 Ohm on-resistance limit. Verify that the 16-pin CDIP footprint matches the PCB layout constraints, as surface-mount alternatives like the DG441DY exist with different pinout considerations.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG441 family of quad SPST analog switches manufactured by Vishay Siliconix. It serves as a through-hole alternative to surface-mount variants, offering enhanced mechanical durability. The AK suffix specifically denotes the ceramic DIP package configuration, distinguishing it from plastic SOIC or PDIP versions within the same electrical family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG221KNZ from Analog Devices Inc. is listed as an available substitute. Verify pin compatibility and electrical parameter alignment, particularly regarding on-resistance and switching speeds, before implementing any cross-manufacturer replacement in existing designs.
