Overview
The DG390ABK is a dual single-pole double-throw (SPDT) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a low on-state resistance of 50 Ohms and operates with supply voltages ranging from ±5V to ±20V for dual supplies or 10V to 40V for single supplies. The device is housed in a 16-CERDIP package, suitable for surface mount or through-hole applications depending on the specific variant configuration, though the ABK suffix typically denotes a ceramic DIP package. It supports signal switching in multiplexing and interface circuits.
Feature Summary
- Dual SPDT analog switch architecture
- Low on-state resistance of 50 Ohms
- Wide dual supply voltage operation range
Applications
- Signal multiplexing
- Interface circuits
- Data acquisition systems
Procurement Notes
Verify component availability as this part may be discontinued or subject to long lead times. Confirm package type matches design requirements. Check RoHS compliance status if environmental regulations apply. Ensure supply voltage ratings align with system specifications before integration.
Selection Notes
Select based on required channel count and on-resistance tolerance. Consider package constraints for PCB layout. Verify operating temperature range meets application needs. Compare against alternative switches if higher speed or lower capacitance is required.
Part Context
Part of the DG390 family of analog switches. Related parts include DG390AAK and DG390ACJ. Designed for precision switching applications requiring low distortion and high isolation.
Replacement Considerations
Check for direct pin-compatible alternatives such as DG390 variants. Evaluate functional equivalents from other manufacturers if original is unavailable. Ensure electrical parameters match or exceed original specifications.
