MAX5426CEUD+

Specialized ICS Overview

The MAX5426CEUD+ is a precision resistor network designed for programmable instrumentation amplifiers. It operates from dual ±5V to ±15V supplies with a supply current of less than 40µA. The device provides noninverting differential gains of 1, 2, 4, and 8, accurate to 0.5% over the -40°C to +85°C temperature range. It features a simple two-bit parallel interface compatible with CMOS/TTL logic. Packaged in a 14-pin TSSOP (6.4mm x 5mm), it includes an offset pin for output adjustment.

Specialized ICS Feature Summary

• Differential gains of 1, 2, 4, and 8 selectable via D1/D0 inputs
• Gain accuracy of 0.5% across extended temperature range (-40°C to +85°C)
• Low power consumption with supply current under 40µA
• CMOS/TTL logic compatible 2-wire parallel digital interface

Specialized ICS Applications

• General-purpose programmable instrumentation amplifiers
• Gain control in RF power amplifiers
• Precision dual attenuator circuits

Specialized ICS Procurement Notes

Verify the specific grade suffix 'C' corresponds to the required 0.5% gain accuracy specification. Confirm the package type matches the 14-TSSOP form factor. Ensure the operating environment stays within the -40°C to +85°C temperature range. Check that the dual supply voltage requirements align with the system design constraints.

Specialized ICS Selection Notes

Select this component when a fixed-accuracy resistor network for instrumentation amplifiers is needed. The C-grade offers 0.5% accuracy; choose A or B grades if tighter tolerances are required. Ensure the application supports dual supplies between ±5V and ±15V. Consider the 14-pin TSSOP footprint during PCB layout planning.

Specialized ICS Part Context

This part belongs to the MAX5426 series of precision resistor networks. Other variants include the MAX5426AEUD+ (0.025% accuracy) and MAX5426BEUD+ (0.09% accuracy). All share the same 14-pin TSSOP package and functional interface but differ in gain accuracy specifications.

Specialized ICS Replacement Considerations

Direct substitutes include other MAX5426 variants with different accuracy grades (A or B). Verify compatibility with existing gain requirements before swapping grades.
