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 225Ω maximum at +5V single supply and 100Ω maximum at ±5V dual supply. The device offers low leakage current (less than 2.5nA at +85°C), charge injection under 5pC, and transition times under 250ns. It maintains rail-to-rail signal handling and provides electrostatic discharge protection exceeding 2000V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE+' corresponds to the commercial temperature range (0°C to +70°C) and the 16-pin Narrow SOIC package configuration. Confirm that the exposed pad requirement for alternative packages does not apply to this specific surface-mount variant. Ensure compatibility with existing PCB footprints designed for standard narrow SOIC dimensions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX398CSE+ when an eight-channel multiplexing solution is required within a compact 16-pin footprint. This part is suitable for applications demanding low power consumption and CMOS logic interface compatibility. Consider the +3V to +15V single-supply operation for battery-powered designs or ±3V to ±8V bipolar supplies for audio and data-acquisition systems requiring rail-to-rail signal handling.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX398CSE+ belongs to the MAX398/MAX399 family of precision analog multiplexers manufactured by Analog Devices Inc./Maxim Integrated. While the MAX399 offers a dual four-channel configuration, the MAX398 provides eight independent channels. Both share identical fabrication processes and electrical characteristics, differing primarily in channel count and pin assignments for address inputs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly states pin compatibility with the DG408, DG409, DG508A, and DG509A. These industry-standard parts serve as direct functional substitutes without requiring schematic modifications.
