MAX5431BEUB+

Overview

The MAX5431BEUB+ is a digitally programmable precision resistor array designed for programmable-gain amplifier (PGA) applications. It operates from single +12V to +15V or dual ±12V to ±15V supplies, consuming only 35µA of supply current. The device provides four noninverting gain configurations (1, 2, 4, and 8) with a ratio accuracy of 0.09%. It features a CMOS/TTL logic compatible 2-wire parallel interface and includes an on-chip matching resistor for op amp input bias-current compensation. The component is housed in a space-saving 10-pin µMAX package and is specified over the extended temperature range of -40°C to +85°C.

Feature Summary

Four Noninverting PGA Gain Configurations: AV = 1, 2, 4, and 8
Precision 0.09% Ratio Accuracy
On-Chip Matching Resistor for Op Amp Bias-Current Compensation
Single-Supply +12V to +15V, or Dual-Supply ±12V to ±15V Operation

Applications

General-Purpose Programmable Noninverting Amplifier
Programmable Instrumentation Amplifier

Procurement Notes

Verify the specific ordering suffix BEUB corresponds to the 10-pin µMAX package and 0.09% accuracy grade when sourcing. Confirm that the component meets RoHS compliance requirements if applicable to the assembly process. Ensure the supplier provides valid traceability documentation for the Analog Devices/Maxim Integrated manufacturer source.

Selection Notes

Select the MAX5431BEUB+ over the MAX5430 variant when input bias-current compensation is required via the integrated matching resistor. Choose this B-grade part for applications requiring 0.09% ratio accuracy rather than the A-grade (0.025%) or C-grade (0.5%). Ensure the design supports the 10-pin µMAX footprint and the specified digital interface voltage levels.

Part Context

This component belongs to the MAX5430/MAX5431 family of digitally programmable high-precision resistor arrays. The MAX5431 variant specifically distinguishes itself by including an on-chip matching resistor, whereas the MAX5430 does not. Both share identical gain structures and interface protocols but differ in internal compensation capabilities.
