MAX4555ESE

Analog Switches - Special Purpose Overview

The MAX4555ESE is a CMOS analog switch IC configured as a force-sense switch for Kelvin sensing in automated test equipment. It contains four independent single-pole/single-throw (SPST) normally closed switches, two low-resistance force switches, and two higher-resistance sense switches. The device operates from a single supply of +9V to +40V or dual supplies of ±4.5V to ±20V. Force switches exhibit a maximum on-resistance of 6Ω with 1Ω matching, while sense switches have a maximum on-resistance of 30Ω with 5Ω matching. Switching times are 275ns maximum for both turn-on and turn-off. Power consumption is 1µA maximum.

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 operation across the full power supply range.
• TTL and CMOS logic compatibility through defined input thresholds ensuring reliable digital control.

Analog Switches - Special Purpose Applications

• Automated Test Equipment (ATE)
• Precision Power Supplies
• Automatic Calibration Circuits

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'ESE' indicates the industrial temperature range (-40°C to +85°C) and narrow SOIC-16 package. Confirm RoHS compliance status via the manufacturer's current documentation. Ensure the ordering code matches the exact pinout and electrical specifications required for the target application design.

Analog Switches - Special Purpose Selection Notes

Select this component when Kelvin sensing is required to eliminate lead resistance errors in precision measurements. The MAX4555 provides four SPST switches suitable for applications needing separate force and sense channels. Compare against MAX4554 and MAX4556 if different channel configurations such as triple-pole or SPDT arrangements are needed instead.

Analog Switches - Special Purpose Part Context

The MAX4555 belongs to the MAX4554/MAX4555/MAX4556 family of force-sense switches manufactured by Analog Devices/Maxim Integrated. These devices are specifically designed for automated test equipment where accurate voltage delivery and measurement are critical. The family shares similar electrical characteristics but differs in internal switch topology and channel configuration.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes within the same family include the MAX4554CSE+ and MAX4556ESE+. Verify that the alternative part number matches the required package type and temperature range. Note that channel configurations differ between these variants.
