DG412AK/883B

Analog Switches, Multiplexers, Demultiplexers Overview

The DG412AK/883B is a quad SPST analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for precision signal routing in harsh environments. It features an 8-pin CERDIP package and operates within a temperature range of -55°C to 125°C. The device supports single supply voltages from 9V to 36V or dual supplies of ±4.5V to ±20V. Key electrical characteristics include a maximum on-resistance of 35 ohms, a channel-to-channel matching of 3 ohms, and a leakage current of 250pA. Switching times are specified at 175ns (Ton) and 145ns (Toff), with a charge injection of 3pC and crosstalk of -85dB at 1MHz.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the specific part number suffix /883B confirms MIL-STD-883 qualification standards required for your application. Confirm the package type matches your PCB footprint requirements. Check for obsolescence status as this component may be subject to limited production runs. Ensure voltage ratings align with your system's power supply specifications before integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high-reliability analog switching is required in extreme temperature conditions. It is appropriate for designs needing low on-resistance variation between channels. Consider alternative packages if surface-mount technology is preferred over ceramic DIP. Evaluate power dissipation limits against your expected duty cycle and ambient thermal conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG41x series of precision analog switches, which includes variants like the DG411 and DG413. These devices share similar performance metrics but differ in configuration and packaging. The DG412 specifically offers a quad SPST layout, distinguishing it from dual or octal configurations found in other family members.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements must maintain MIL-STD-883 certification and identical pinout compatibility. Verify that substitute parts offer comparable on-resistance and switching speed specifications. Ensure the replacement package matches the 8-CERDIP form factor for mechanical fit.
