MAX398EEE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX398EEE+T is a precision, monolithic CMOS analog multiplexer housed in a 16-pin QSOP package. It provides eight bidirectional channels with a single common output. The device operates on a +3V to +15V single supply or ±3V to ±8V bipolar supplies. Key electrical parameters include an on-resistance of 100 Ω maximum at dual supplies and 225 Ω maximum at single supplies. Leakage current is less than 2.5nA at +85°C. The component supports a -40°C to +85°C operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EEE corresponds to the QSOP-16 package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure logic input voltage levels align with system requirements for reliable switching operation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when pin compatibility with legacy DG4xx series switches is required. Consider the lower on-resistance specifications if utilizing dual supplies compared to single-supply configurations. Evaluate thermal dissipation limits based on the specific QSOP package power derating curves provided in the datasheet.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX398/MAX399 family of precision analog multiplexers manufactured by Analog Devices/Maxim Integrated. The MAX398 variant specifically offers eight channels, whereas the MAX399 provides two independent four-channel sets. Both share identical fabrication processes and core performance characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations
