Overview
The DG381ACJ+ is a dual single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within 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 with a maximum turn-on time of 300 ns and a maximum turn-off time of 250 ns. It is housed in a 14-pin PDIP package and functions within an operating temperature range of 0°C to +70°C.
Feature Summary
- Dual SPST configuration providing two independent signal paths
- CMOS technology enabling low power consumption
- Normally open operation for standard switching applications
Applications
- General purpose analog signal routing
- Data acquisition systems
- Instrumentation signal conditioning
Procurement Notes
Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance details as documentation may vary. Check for lead-free plating specifications if required by assembly processes. Validate package integrity upon receipt to ensure pin alignment matches the 14-PDIP footprint.
Selection Notes
Select this component when dual isolated channels are required without cross-talk interference. Ensure supply voltages remain within the ±18 V dual limit to prevent damage. Consider thermal dissipation limits of 470 mW during continuous operation. Verify that the 50 Ohm on-resistance meets the specific circuit impedance requirements.
Part Context
This part belongs to the DG381A series of analog switches. It shares functional similarities with other devices in the family but differs in packaging and specific electrical tolerances. The suffix 'C' typically denotes commercial temperature grading, while 'J+' indicates the through-hole PDIP package variant with lead-free composition.
Replacement Considerations
Direct substitutes include the DG381ACJ non-plus version for identical electrical performance without lead-free constraints. The DG381ACWE+ serves as a surface-mount alternative using the SOIC-Wide-16 package. Cross-reference with DG303ACJ+ if SPDT functionality is acceptable instead of SPST.
