DG201ACSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201ACSE+ is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on dual power supplies ranging from ±4.5V to ±18V and utilizes a monolithic low-power CMOS design. The device features normally closed contacts with guaranteed break-before-make switching. Electrical specifications include a maximum turn-on time of 600ns, a maximum turn-off time of 450ns, and an on-resistance of up to 200Ω at ±15V supply. It is housed in a 16-pin SOIC package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official manufacturer documentation to confirm pinout compatibility and electrical ratings. Ensure the specific ordering suffix matches the required temperature range and package style for your application. Cross-reference datasheet parameters such as on-resistance and leakage current to validate suitability for signal integrity requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring normally closed analog switching within a ±4.5V to ±18V supply range. Consider the 600ns turn-on and 450ns turn-off times when evaluating signal timing constraints. Verify that the 16-SOIC package dimensions fit the PCB layout and that the 0°C to +70°C operating temperature aligns with environmental conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG201A series consists of quad SPST CMOS analog switches designed for portable and general-purpose applications. The DG201ACSE+ variant specifically denotes the commercial temperature grade and surface-mount SOIC packaging. This part belongs to a family that includes variants like the DG211, which offers different switching speeds but shares similar operational characteristics and pin configurations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the same family include the DG211CSE+, which offers slightly slower switching speeds but maintains identical pinouts and functionality. Other package variations such as the DG201ACJ+ (DIP) or DG201ACUE+ (TSSOP) provide alternative mounting options with equivalent electrical performance.
