Overview
The DG305ACWE+ is a single-channel CMOS analog switch configured as a single-pole double-throw (SPDT) circuit. It operates within a supply voltage range of ±5 V to ±18 V and supports dual power supplies. The device features a maximum on-resistance of 50 Ohms and handles a DC switch current of 30 mA. Switching performance includes a maximum turn-on time of 250 ns and a maximum turn-off time of 150 ns. Power dissipation is rated at 470 mW, with a maximum supply current of 10 uA. It functions in an operating temperature range from 0°C to +70°C and is housed in a 16-SOIC surface-mount package.
Feature Summary
- CMOS technology ensures low power consumption and high input impedance for efficient signal routing.
- Single SPDT configuration provides flexible signal path selection between two outputs.
- Low on-resistance characteristic maintains signal integrity across the operational bandwidth.
Applications
- Signal multiplexing in data acquisition systems
- Audio and video signal switching applications
- Instrumentation front-end signal routing
Procurement Notes
Verify component authenticity through authorized distribution channels or direct manufacturer verification. Confirm RoHS compliance status and specific lot traceability requirements prior to integration. Ensure storage conditions adhere to moisture sensitivity level guidelines to prevent package damage during soldering processes.
Selection Notes
Select this component when a single SPDT switch with moderate speed and low on-resistance is required. Verify that the system supply voltage falls within the ±5 V to ±18 V range. Consider the 16-SOIC package dimensions for PCB layout constraints and ensure thermal management accommodates the specified power dissipation limits under maximum load conditions.
Part Context
This part belongs to the DG305A series of CMOS analog switches manufactured by Analog Devices Inc./Maxim Integrated. It shares functional similarities with other devices in the DG304/305/306 family but is distinguished by its specific channel count and packaging. The suffix 'WE+' indicates the 16-SOIC surface-mount package and lead-free compliant construction.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Engineering teams should consult official cross-reference guides or contact the manufacturer directly for validated alternatives compatible with the DG305ACWE+ specifications.
