MAX398ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX398ESE is a precision, monolithic CMOS analog multiplexer featuring eight channels in a 16-pin Narrow SOIC package. It operates from a single +3V to +15V supply or bipolar ±3V to ±8V supplies. Key electrical parameters include an on-resistance of 100 Ω maximum and flatness of 11 Ω maximum over the signal range. Channel matching is guaranteed within 6 Ω. The device provides low off-leakage current (2.5 nA max at +85°C) and charge injection under 5 pC. Switching speeds feature a transition time of 250 ns maximum and enable turn-on/off times up to 200 ns.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' confirms the -40°C to +85°C industrial temperature rating and 'SE' indicates the 16-pin Narrow SOIC package. Confirm RoHS compliance status as '+', if required by your design specifications. Ensure the exposed pad connection requirements are met during PCB layout to maintain thermal performance and electrical integrity.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel configuration is required rather than the dual 4-channel MAX399. Verify that the single-supply or bipolar voltage rails match the system's power architecture. Consider the 100 Ω on-resistance limit against the load requirements. Ensure the logic input levels align with the system's digital control voltages for reliable switching operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX398 belongs to the Maxim Integrated precision analog multiplexer family. It shares architectural similarities with the MAX399 but differs in channel count. The device utilizes a low-voltage silicon-gate process designed for fast switching and low power consumption. It serves as a direct replacement for legacy discrete analog switch solutions in compact designs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes include the DG408, DG409, DG508A, and DG509A. Verify that the alternative device meets the specific on-resistance flatness and leakage current requirements of the original design before implementation.
