DG390AAK

Overview

The DG390AAK is a single-pole double-throw (SPDT) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two functional blocks within a single channel configuration, utilizing CMOS technology for low power consumption. The device operates with a nominal supply voltage of 15V and supports negative supply rails down to -15V. It is housed in a ceramic dual in-line package (CDIP) with 16 pins, designed for high-reliability applications requiring glass-sealed construction. The component exhibits a maximum on-resistance of 50 ohms and provides typical off-isolation of 62 dB at standard operating conditions.

Feature Summary

• Utilizes CMOS technology for efficient signal switching with low power requirements.
• Features a robust ceramic package with glass sealing for enhanced environmental protection and reliability.
• Supports dual function configurations within a single-channel architecture for compact circuit design.

Applications

• High-reliability aerospace and defense signal routing systems
• Industrial instrumentation requiring hermetic sealing
• Test and measurement equipment demanding stable analog switching

Part Context

The DG390 series belongs to the family of high-performance analog switches from Maxim Integrated. These components are distinguished by their use of CMOS processes combined with specialized packaging options like CDIP for harsh environments. The DG390AAK specifically denotes the ceramic variant, offering superior durability compared to standard plastic packages while maintaining comparable electrical performance metrics for general-purpose analog signal path control.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Engineers should verify pin compatibility and package dimensions when considering alternative SPDT switches from the same manufacturer or other vendors offering hermetic ceramic packages.
