MAX398EEE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX398EEE+ is a precision, monolithic CMOS analog multiplexer featuring an 8-channel configuration housed in a 16-pin QSOP package. It operates with a single +3V to +15V supply or bipolar ±3V to ±8V supplies. The device guarantees low on-resistance of less than 100 Ω, matched within 6 Ω between channels, and flatness of 11 Ω maximum over the signal range. Key electrical parameters include off-leakage current under 2.5 nA at +85°C, charge injection below 5 pC, and transition times under 250 ns. It provides electrostatic discharge protection exceeding 2000V and maintains rail-to-rail signal handling capabilities.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'EEE+' corresponds to the -40°C to +85°C temperature range and QSOP package variant. Request original datasheets and RoHS compliance documentation to ensure adherence to environmental standards before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing systems requiring precise analog signal routing with minimal resistance variation across multiple channels. Ensure the operating voltage aligns with the specified single or dual supply ranges. Verify that the thermal environment remains within the industrial temperature limits defined for the EEE+ suffix to maintain guaranteed performance specifications.

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 provides eight independent channels, whereas the MAX399 offers two dual four-channel configurations. Both share identical pinouts and core electrical characteristics, differing primarily in channel count and internal decoder logic.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX398EEE+ is explicitly designed as a drop-in replacement for industry-standard parts including the DG408, DG409, DG508A, and DG509A due to pin compatibility. When substituting, verify that the alternative device meets the required on-resistance matching and leakage current specifications for the application.
