DG201ADY+T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201ADY+T is a quad single-pole single-throw (SPST) normally-closed analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features four independent channels within a 16-pin SOIC package. The device operates on dual power supplies ranging from ±4.5V to ±18V, with a maximum supply voltage of 36V. Key electrical parameters include a maximum on-resistance of 200 ohms and a maximum leakage current of 5nA in the off state. Switching times are specified at a maximum turn-on time of 600ns and a maximum turn-off time of 450ns. The component supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• CMOS technology enables low power consumption and high input impedance

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring signal routing
• Industrial process control instrumentation
• Audio signal switching and multiplexing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the 'ADY' designation corresponds to the industrial temperature grade and SOIC-16 package variant. Ensure compatibility with existing PCB footprints for 16-pin narrow-body packages before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring normally-closed logic states upon power-up. Compare on-resistance specifications against signal integrity requirements. Verify that the ±18V maximum supply rating aligns with system power rails. Consider thermal dissipation limits if multiple channels are active simultaneously.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG201 family of CMOS analog switches. It serves as a functional alternative to other quad SPST switches in data acquisition chains. The device complements multiplexer families like the DG408 by providing simple channel isolation rather than complex routing.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the DG201ACJ+ and DG201BDJ. Verify pinout compatibility and package dimensions (SOIC vs DIP) when replacing. Check if the replacement part meets the same normally-closed specification and on-resistance limits.
