MAX398CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX398CSE is a precision, monolithic CMOS analog multiplexer featuring eight channels in a 16-pin Narrow SOIC package. It operates with single +3V to +15V or bipolar ±3V to ±8V supplies. Key electrical parameters include an on-resistance of 280Ω maximum at +5V single supply and 14Ω maximum at ±5V dual supply. The device ensures channel-to-channel matching within 13Ω and maintains low off-leakage current below 2.5nA at +85°C. Switching speeds are characterized by transition times under 250ns and charge injection less than 5pC.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' corresponds to the commercial temperature range (0°C to +70°C) and the narrow SOIC package format. Confirm that the ordering information matches the exact pinout and exposed pad requirements if utilizing QFN variants, as package codes differ significantly across the MAX398 family.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexing solution is required with low-voltage operation capabilities. Ensure the application demands high on-resistance flatness and minimal charge injection. Verify that the logic input voltage levels align with the specified TTL/CMOS compatibility thresholds for reliable switching control.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX398CSE belongs to the MAX398/MAX399 series of precision analog multiplexers manufactured by Analog Devices Inc./Maxim Integrated. This series is designed for applications requiring low distortion and fast switching in compact form factors. The CSE designation specifically identifies the commercial grade variant housed in a standard narrow surface-mount package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the DG408, DG409, DG508A, and DG509A due to guaranteed pin compatibility. Other MAX398 variants such as MAX398ESE or MAX398EEE offer extended temperature ranges but require verification of thermal specifications.
