MAX5426BEUD+T

Specialized ICS Overview

The MAX5426BEUD+T is a precision resistor network designed for programmable instrumentation amplifiers. It provides differential gains of 1, 2, 4, and 8 with an accuracy of 0.09% over the extended temperature range of -40°C to +85°C. The device operates from dual ±5V to ±15V supplies and consumes less than 40µA of supply current. It features a simple CMOS/TTL logic compatible 2-wire parallel interface for gain selection and includes an offset pin for output adjustment.

Specialized ICS Procurement Notes

Verify the package type (14-TSSOP) and temperature range (-40°C to +85°C) against your design requirements. Ensure that the power supply rails are within the specified ±5V to ±15V range. Check for any specific ordering suffixes or alternative grades if higher accuracy is needed.

Specialized ICS Selection Notes

Select this component when high-precision gain settings are required for instrumentation amplifiers. Consider the 0.09% gain accuracy and low supply current. Ensure the application supports dual supply operation and utilizes a 2-wire digital interface for control.

Specialized ICS Part Context

The MAX5426 series includes variants with different gain accuracies: MAX5426AEUD (0.025%), MAX5426BEUD (0.09%), and MAX5426CEUD (0.5%). All variants share the same 14-pin TSSOP package and functional characteristics, differing primarily in their gain accuracy specifications.

Specialized ICS Replacement Considerations

Direct replacements include MAX5426AEUD+T for higher accuracy (0.025%) and MAX5426CEUD+T for lower accuracy (0.5%). Ensure the substitute part matches the 14-TSSOP package and operating voltage range.
