Overview
The DG423DN is a dual SPDT analog switch IC manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a PLCC-20 surface-mount package. It operates on single or dual power supplies ranging from 10 V to 30 V (single) or ±4.5 V to ±20 V (dual). Key electrical parameters include a maximum on-resistance of 45 Ohms, a maximum switching time of 250 ns, and a maximum off-time of 200 ns. The device supports a DC switch current of 20 mA with a maximum power dissipation of 800 mW and a maximum supply current of 1 uA. It functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Dual single-pole double-throw (SPDT) configuration for signal routing
- Low power consumption suitable for battery-operated systems
- High isolation between switched channels
Applications
- Signal multiplexing in data acquisition systems
- Audio and video signal routing
- Instrumentation front-end switching
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinued status. Confirm RoHS compliance requirements as indicated specifications may vary by production batch. Ensure proper handling procedures for the PLCC-20 package during assembly to prevent mechanical damage.
Selection Notes
Select this component when dual SPDT switching functionality is required with moderate speed and low power constraints. Verify that the 45 Ohm on-resistance meets system accuracy requirements. Ensure supply voltage ranges align with available power rails in the target design.
Part Context
The DG423 belongs to the DG423 series of CMOS analog switches. It is part of Analog Devices' portfolio acquired from Maxim Integrated. The DN suffix denotes the PLCC-20 plastic leaded chip carrier package variant.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official replacement guides for legacy component cross-references.
