DG509AAK/883B

Analog Switches, Multiplexers, Demultiplexers Overview

The DG509AAK/883B is a dual-channel, single-ended analog multiplexer manufactured by Analog Devices under the Maxim Integrated brand. It features an 8:1 configuration per channel, totaling two independent switching circuits within a single package. The device utilizes CMOS technology and operates on a ceramic dual in-line package (CDIP) with 16 pins. It supports dual power supplies ranging from ±4.5V to ±18V. Key electrical specifications include a maximum on-resistance of 450 Ohms and a channel-to-channel on-resistance match of 27 Ohms. Switching times are specified with a maximum turn-on time of 1.5µs and a maximum turn-off time of 1µs. The component is designed for military or high-reliability applications, indicated by the /883B suffix.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the authenticity of the /883B suffix, which denotes compliance with MIL-PRF-38534 standards. Confirm that the ceramic package matches the required pinout and thermal characteristics for the target application. Check for recent Product Change Notices regarding manufacturing origin changes, as this part may be produced by multiple qualified vendors under license. Ensure proper handling procedures for ceramic packages are followed during assembly.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent 8-channel switching is required in a space-constrained layout. Compare the 450 Ohm on-resistance against load requirements to ensure acceptable voltage drop. Verify that the ±4.5V to ±18V supply range aligns with system power rails. Consider the 1.5µs switching speed if signal bandwidth or update rates are critical constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG509A series of CMOS analog multiplexers. It shares functional similarities with the DG508A but offers dual channels instead of a single 8-channel mux. The /883B designation distinguishes it from commercial variants like DG509ACJ by ensuring higher reliability and radiation hardness suitable for defense applications.
