DG381ACJ

Overview

The DG381ACJ is a dual single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates with a supply voltage range of 10 V to 30 V for single supplies or ±5 V to ±18 V for dual supplies. The device features a maximum on-resistance of 50 Ohms and supports a DC switch current of 30 mA. Switching times are specified at a maximum of 300 ns for turn-on and 250 ns for turn-off. It functions within an operating temperature range of 0°C to +70°C and is housed in a 14-pin PDIP package.

Feature Summary

• Dual SPST configuration providing independent signal path control
• CMOS technology enabling low power consumption and high input impedance
• Normally open state ensuring defined default signal blocking

Applications

• General purpose analog signal routing
• Data acquisition systems
• Instrumentation signal conditioning

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance details as specifications may vary by production batch. Validate package integrity upon receipt to ensure pin alignment matches the 14-PDIP footprint requirements for your design.

Selection Notes

Select this component when dual isolated analog switching is required within standard industrial temperature limits. Ensure supply voltages remain within the 10 V to 30 V single or ±5 V to ±18 V dual range. Consider the 50 Ohm on-resistance limit for signal integrity requirements in your specific application circuit.

Part Context

This part belongs to the DG381A series of general-purpose analog switches. It shares functional similarities with other devices in the Maxim Integrated portfolio designed for basic signal switching tasks. The ACJ suffix specifically denotes the commercial temperature grade and plastic DIP packaging variant.

Replacement Considerations

Public confirmed substitute part numbers include DG381ACWE+ and DG381ACJ+. Verify pin compatibility and package dimensions before substitution.
