Overview
The DG181BA is a dual analog switch manufactured by Rochester Electronics, LLC. It operates within a supply voltage range of 3V to 20V and supports both single and dual power supplies. The device features low on-resistance and excellent signal integrity for analog signal routing. It utilizes a CMOS process technology to ensure low power consumption and high noise immunity. The component is housed in a compact surface-mount package suitable for space-constrained designs.
Feature Summary
- Dual-channel analog switching capability
- Wide single or dual supply voltage operation
- Low on-resistance for minimal signal loss
- High noise immunity due to CMOS construction
Applications
- Signal multiplexing in data acquisition systems
- Audio signal routing and switching
- Instrumentation and test equipment
- Communication systems requiring analog switching
Procurement Notes
Verify the manufacturer marking and date code against the specific lot requirements. Confirm the package type matches the design footprint. Check for any lead-free or RoHS compliance documentation if required by the end product regulations. Ensure the storage conditions meet the moisture sensitivity level specifications before assembly.
Selection Notes
Select this component when dual independent analog switches are required with wide supply voltage flexibility. Consider the on-resistance and leakage current specifications relative to the signal amplitude. Evaluate the package size constraints against available board space. Compare performance metrics with other CMOS analog switches for optimal system integration.
Part Context
Rochester Electronics specializes in sourcing and distributing obsolete and hard-to-find electronic components. The DG181BA represents a continuation of availability for legacy parts originally produced by other manufacturers. This component serves as a replacement source for designs that cannot be easily migrated to newer technologies.
Replacement Considerations
Check pinout compatibility with original designs. Verify electrical parameters such as on-resistance and breakdown voltage match the application requirements. Review package dimensions to ensure mechanical fit. Consult official substitution guides for equivalent functionality.
