MAX5422ETA

Overview

The MAX5422ETA is a single-channel, nonvolatile digital potentiometer manufactured by Analog Devices Inc./Maxim Integrated. It features a resistance value of 50 kOhms with 256 taps and utilizes an SPI interface for control. The device operates within a supply voltage range of 2.7V to 5.25V and is housed in an 8-TDFN (3x3) package. It maintains a typical temperature coefficient of 35ppm/°C and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

Nonvolatile memory retains wiper position after power loss
SPI serial interface for data transfer
Single circuit configuration with 256 tap resolution
Linear taper characteristic

Applications

Programmable gain amplifiers
Voltage reference adjustment
Sensor signal conditioning

Procurement Notes

Verify the specific suffix 'T' if tape-and-reel packaging is required, as the base part number may denote tube packaging. Confirm RoHS compliance status (+ suffix) against current regulatory requirements. Check lead times and availability through authorized distributors, as stock levels fluctuate based on production cycles.

Selection Notes

Select this component when a compact, low-power digital potentiometer with persistent settings is needed. Ensure the 50kOhm resistance value matches the circuit impedance requirements. Verify that the SPI interface compatibility exists with the host microcontroller. Consider the 8-TDFN package dimensions for PCB layout constraints.

Part Context

This component belongs to the MAX5422 family of digital potentiometers. It shares architectural similarities with other Maxim Integrated digital pots but is distinct in its specific resistance value and interface type. The family is designed for applications requiring precise, software-adjustable resistance without mechanical wear.

Replacement Considerations

Direct replacements include other MAX5422 variants with different resistance values or packaging options. Cross-reference with similar SPI-based digital potentiometers from other manufacturers only if pinout and electrical specifications are fully compatible.
