MAX396EWI

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX396EWI+ is a precision, low-voltage CMOS analog multiplexer featuring 16 single-ended channels in a 28-pin Wide SO package. It operates with a single supply from +2.7V to +16V or dual supplies of ±2.7V to ±8V. Key electrical characteristics include a maximum on-resistance of 100Ω at ±5V and 550Ω at +3V single supply, with guaranteed matching within 6Ω and flatness within 10Ω. The device offers fast switching speeds, with transition times under 250ns at ±5V and charge injection limited to 5pC. Input off-leakage current remains below 1nA at +85°C, ensuring high signal integrity across the -40°C to +85°C operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EWI+' corresponds to the Wide SOIC-28 package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ordering details match the exact pinout and functional specifications required for the target design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX396EWI+ when a 16-channel configuration is required instead of the dual 8-channel MAX397. Consider the wider SOIC package for surface-mount assembly needs. Evaluate the higher on-resistance at lower single-supply voltages (+3V) against system requirements compared to dual-supply operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

Part of the MAX396/MAX397 family of precision analog multiplexers fabricated using low-voltage silicon-gate CMOS processes. Designed as a direct replacement for legacy parts like the MAX306 and DG406, offering improved performance metrics such as lower charge injection and faster switching speeds while maintaining standard pinouts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the MAX306, DG406, and DG506A. Verify that substitute components meet the specific on-resistance and leakage requirements of the original design.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the on-resistance vary with supply voltage?

On-resistance increases significantly at lower supply voltages. It is guaranteed at 100Ω max with ±5V supplies but rises to 550Ω max with a +3V single supply.

What is the ESD protection level?

The device guarantees electrostatic-discharge (ESD) protection greater than 2000V per Method 3015.7.

Can the device operate with unbalanced supplies?

Yes, the MAX396 supports unbalanced supply configurations, such as +10V and -5V, provided the difference between V+ and V- does not exceed 17V.
