MAX4554CSE+

Analog Switches - Special Purpose Overview

The MAX4554CSE+ is a CMOS analog switch IC configured as a force-sense switch for Kelvin sensing in automated test equipment. It contains two triple-pole/single-throw (3PST) normally open switches, each comprising one high-current low-resistance force path, one sense path, and one guard path. The device operates from single supplies of +9V to +40V or dual supplies of ±4.5V to ±20V. Force switches exhibit a maximum on-resistance of 6Ω with matching up to 1Ω. Sense and guard switches have a maximum on-resistance of 60Ω with matching up to 8Ω. The part supports Rail-to-Rail analog signals, features off-leakage current of 0.25nA at +25°C, and includes TTL/CMOS-compatible digital inputs.

Analog Switches - Special Purpose Feature Summary

• Integrated force-sense architecture enabling precise Kelvin sensing by separating high-current forcing paths from low-current voltage sensing paths.
• Rail-to-Rail signal handling capability allowing the switches to process analog signals across the full supply voltage range.
• TTL and CMOS logic input compatibility ensuring straightforward interfacing with standard digital control circuits.

Analog Switches - Special Purpose Applications

• Automated Test Equipment (ATE)
• Precision Calibrators
• Automatic Calibration Circuits

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'CSE+' against the manufacturer's official documentation to confirm the package type, temperature range, and lead-free status. Ensure that the ordering information matches the required operational specifications before procurement.

Analog Switches - Special Purpose Selection Notes

Select this component when Kelvin sensing is required for precision measurements. Compare the MAX4554 against the MAX4555 and MAX4556 based on the necessary switch configuration, specifically the number of force, sense, and guard channels needed for the application.

Analog Switches - Special Purpose Part Context

The MAX4554CSE+ belongs to the MAX4554/MAX4555/MAX4556 family of force-sense switches manufactured by Analog Devices / Maxim Integrated. These devices are designed to overcome conductor resistance errors in high-current applications through dedicated sensing and guarding capabilities.

Analog Switches - Special Purpose Replacement Considerations

The MAX4555 and MAX4556 are pin-compatible members of the same family but offer different internal switch configurations. Verify functional equivalence regarding channel types before substitution.
