MAX5430BEKA

Overview

The MAX5430BEKA+ is a digitally programmable precision voltage divider manufactured by Analog Devices (Maxim Integrated). It features an R-2R resistor network architecture housed in an SOT-23-8 surface-mount package. The device operates within a supply voltage range of 4.75 V to 15.75 V and supports an industrial temperature range from -40°C to +85°C. Key performance specifications include a differential nonlinearity (DNL) and integral nonlinearity (INL) of ±0.5 LSB, ensuring high accuracy for signal conditioning applications.

Feature Summary

• 16-bit resolution with R-2R architecture
• Serial interface control via 3-wire connection
• ±0.5 LSB DNL and INL linearity
• SOT-23-8 compact surface-mount packaging

Applications

• Programmable gain amplifiers
• Variable voltage references
• Sensor signal conditioning

Procurement Notes

Verify the specific suffix 'EKA' against official Analog Devices documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status through current manufacturer datasheets. Check authorized distributor availability as lead times may vary for this component series.

Selection Notes

Select the MAX5430BEKA+ when a compact, high-resolution digital potentiometer or voltage divider is required. Ensure the application voltage does not exceed the maximum rating of 15.75 V. Compare against the MAX5430A variant if extended temperature ranges beyond +85°C are necessary for the specific design environment.

Part Context

This component belongs to the MAX5430 family of digitally programmable voltage dividers. It serves as a solid-state alternative to mechanical potentiometers, offering improved reliability and smaller footprint in space-constrained electronic designs requiring precise analog signal adjustment.

Replacement Considerations

The MAX5430AEKA+ is a verified equivalent within the same product family, differing primarily in temperature grade specifications. Verify pin compatibility before substitution.
