Overview
The DG423DJ 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 10V to 30V (single) or ±4.5V to ±20V (dual). Key electrical parameters include a maximum on-resistance of 45 Ohms, a maximum supply current of 1 µA, and a DC switch current of 20 mA. The device supports a maximum data rate with a turn-on time of 250 ns and a turn-off time of 200 ns. It functions within an operating temperature range of -40°C to +85°C and has a maximum power dissipation of 800 mW.
Feature Summary
- Dual single-pole double-throw (SPDT) switching configuration for signal routing
- Low power consumption suitable for battery-operated applications
- High input impedance and low leakage current characteristics
Applications
- Data acquisition systems requiring signal multiplexing
- Audio and video signal switching circuits
- Process control instrumentation
Procurement Notes
Verify component authenticity through authorized distributors due to potential availability constraints. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices or lifecycle changes prior to procurement planning. Ensure packaging specifications match design requirements for PLCC-20 footprint compatibility.
Selection Notes
Select this component when dual SPDT switching with low on-resistance is required. Consider the PLCC-20 package size against board space limitations. Evaluate power supply voltage ranges to ensure compatibility with system rails. Compare performance metrics against alternative switches if higher channel counts or faster switching speeds are needed.
Part Context
The DG423DJ belongs to the DG423 series of CMOS analog switches. This series is designed for general-purpose signal switching applications. The part number suffix 'DJ' typically denotes the specific package type and temperature grade within the product family. It shares functional similarities with other devices in the Maxim Integrated analog switch portfolio.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Verify pinout compatibility and electrical parameter equivalence before replacing. Check for updated versions or enhanced performance variants within the same manufacturer's lineup.
