DG201ABK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201ABK is a quad single-pole single-throw (SPST) normally-closed analog switch manufactured by Analog Devices Inc./Maxim Integrated. It utilizes CMOS technology to provide four independent signal paths within a compact package. The device supports dual power supplies ranging from ±4.5V to ±18V, enabling robust signal switching capabilities. Key electrical parameters include a maximum on-resistance of 200 ohms and low leakage current. It operates within a commercial temperature range of 0°C to 70°C and is housed in an 8-SOIC surface-mount package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrates four independent SPST switches for multi-channel signal routing
• Normally-closed configuration ensures default signal continuity
• CMOS construction provides low power consumption and high input impedance

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal multiplexing in data acquisition systems
• Audio and video signal path switching
• Instrumentation front-end protection

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'BK' against official manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status as older Maxim variants may differ. Check for end-of-life notifications or obsolescence notices prior to finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally-closed logic state is required for the idle condition. Ensure the supply voltage remains within the ±4.5V to ±18V range to maintain specified on-resistance characteristics. Verify that the 200-ohm on-resistance meets the application's signal integrity requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG201 family of analog switches, which also includes variants like the DG201ACJ. The family is characterized by its quad SPST architecture and CMOS process technology. Different suffixes typically denote variations in packaging or temperature ratings rather than functional differences.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG201AKNZ is a documented replacement for the DG201A series. Verify pin compatibility and ensure the normally-open configuration of the ADG201 does not conflict with the normally-closed requirement of the original design.
