Overview
The DG390ACJ+ is a dual single-pole double-throw (SPDT) CMOS analog switch manufactured by Analog Devices / Maxim Integrated. It operates within a supply voltage range of ±5V to ±18V for dual supplies or 10V to 36V for single supplies. The device features a maximum on-state resistance of 50 Ohms and supports a continuous DC switch current of 20 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 16-pin PDIP package and functions reliably across an operating temperature range of 0°C to +70°C.
Feature Summary
- Dual SPDT configuration providing two independent signal routing paths
- CMOS technology enabling low power consumption and high input impedance
- Symmetrical switching characteristics for accurate signal transmission
Applications
- Signal multiplexing and demultiplexing in data acquisition systems
- Audio and video signal routing applications
- Test and measurement equipment requiring precise analog switching
Procurement Notes
Verify the specific suffix designation, as the provided model lacks the standard '+' indicator often associated with lead-free compliance. Confirm RoHS status directly from the manufacturer datasheet, as historical variants may differ. Ensure the 16-DIP through-hole package matches the target PCB footprint requirements before finalizing procurement decisions.
Selection Notes
Select this component when dual independent SPDT switching is required within a single package. Compare the 50 Ohm on-resistance against application tolerance limits. Verify that the ±18V maximum dual supply rating aligns with system voltage rails. Consider the 300 ns switching speed suitability for the intended signal frequency bandwidth.
Part Context
This component belongs to the DG3xx series of general-purpose analog switches. It shares architectural similarities with the DG303 and DG381 but differs in pin count and configuration. The DG390 specifically offers dual SPDT functionality in a 16-pin format, distinguishing it from the dual SPST devices found in smaller packages.
Replacement Considerations
The DG390ACJ+ is listed as active in some distributor records. Direct pin-compatible substitutes include other dual SPDT CMOS switches from the same family, such as the DG303ACJ+, provided the package and electrical specifications match the design requirements.
