DG381ACWE+

Overview

The DG381ACWE+ is a dual single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with a maximum on-resistance of 50 Ohms and supports single or dual power supplies ranging from 10 V to 30 V, or ±5 V to ±18 V. The device features a maximum turn-on time of 300 ns and a turn-off time of 250 ns. It is housed in a 16-SOIC surface-mount package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Dual SPST configuration for independent signal routing
• CMOS technology enabling low power consumption
• TTL/CMOS logic interface compatibility

Applications

• General-purpose analog signal switching
• Data acquisition systems
• Audio and video signal routing

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Check RoHS compliance documentation carefully as legacy variants may differ. Confirm package integrity upon receipt. Validate datasheet revisions against current design requirements before integration.

Selection Notes

Select this component for applications requiring dual isolated channels with moderate speed. Ensure supply voltage stays within the 10 V to 30 V single or ±5 V to ±18 V dual range. Verify thermal management for the SOIC-Wide-16 package. Consider pinout compatibility if replacing older DG381A variants.

Part Context

This part belongs to the DG381A series of general-purpose analog switches. It shares functional similarities with the DG300A but differs in specific electrical characteristics and packaging options. The 'WE' suffix indicates the wide-body SOIC package variant.

Replacement Considerations

Public confirmed substitutes include DG381ACJ+ for through-hole applications. Direct replacements must maintain the 16-pin SOIC footprint and dual SPST configuration.
