MAX397EWI

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX397EWI+ is a dual, 8-channel low-voltage CMOS analog multiplexer. It operates with single supplies from +2.7V to +16V or dual supplies from ±2.7V to ±8V. The device features a maximum on-resistance of 100Ω, guaranteed matching within 6Ω between channels, and flatness over the signal range up to 10Ω. It provides fast switching speeds with transition times under 250ns and extremely low charge injection of 5pC maximum. The component includes ESD protection exceeding 2000V and maintains TTL/CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EWI' corresponds to the Wide SOIC package and the '-E' grade indicating the -40°C to +85°C operating temperature range. Confirm RoHS compliance status through official documentation as manufacturing processes evolve. Ensure the ordering code matches the exact pin configuration required for the target PCB layout.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 8-channel configuration is required rather than a single 16-channel unit. Verify that the supply voltage range aligns with the system's power rails. Consider the on-resistance characteristics relative to the load impedance to ensure signal integrity. Check if the Wide SOIC package dimensions fit the available board space constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX396/MAX397 family of precision analog multiplexers. While the MAX396 offers a single 16-channel configuration, the MAX397 provides two independent 8-channel sets. Both share identical electrical specifications and are designed for low-voltage applications requiring high performance and reliability in data acquisition systems.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX397EWI is pin-compatible with the MAX307, DG407, and DG507A. These alternatives can be considered for direct replacement if they meet the specific voltage and temperature requirements of the design.
