DG390ACJ+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG390ACJ+ is a dual single-pole double-throw (SPDT) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on dual power supplies ranging from ±5V to ±18V and supports through-hole mounting in a 16-DIP package. The device features a maximum on-state resistance of 50 Ohms, with turn-on and turn-off times of 300ns and 250ns respectively. It exhibits low leakage current of 5nA maximum, charge injection of 12pC, and channel capacitance of 14pF. Crosstalk performance reaches -74dB at 500kHz, ensuring signal integrity within its specified operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure packaging integrity matches specification standards for DIP-16 components. Review datasheet revisions for any parameter updates prior to finalizing supply agreements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent SPDT switching is required within standard voltage ranges. Consider the 50 Ohm on-resistance limit for signal attenuation calculations. Verify that the ±5V to ±18V supply range aligns with system power architecture. Evaluate thermal dissipation capabilities within the 0°C to +70°C operational envelope for environmental compatibility.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG390ACJ+ belongs to the broader family of CMOS analog switches designed for general-purpose signal routing. It complements other devices like the DG381 and DG200 series by offering SPDT functionality rather than SPST configurations. This part serves as a foundational building block for creating complex switching matrices in industrial and consumer electronics applications requiring reliable analog signal control.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the DG390AN and DG390CN variants which share identical electrical specifications but differ in package type or temperature rating. Cross-reference pinouts and on-resistance values when evaluating alternative manufacturers' offerings to ensure functional equivalence in existing circuit designs.
