MAX5475EKA

Overview

The MAX5475EKA+T is a single-channel digital potentiometer IC featuring 32 nonvolatile taps and linear taper characteristics. It operates within a supply voltage range of 2.7 V to 5.25 V, drawing a typical operating current of 1 µA. The device utilizes an Up/Down digital interface for wiper position control and offers a resistance value of 100 kOhms with a temperature coefficient of 35 PPM/°C. Packaged in an SOT-23-8 surface-mount format, it supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Nonvolatile memory retains wiper settings without power
• Single channel with 32 discrete tap positions
• Low power consumption of 1 µA typical operating current
• Linear taper resistance profile

Applications

• Programmable gain amplifiers
• Voltage reference adjustment
• Sensor biasing networks

Procurement Notes

Verify the specific suffix (e.g., T for tape and reel) against the required packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the Up/Down interface compatibility matches the system controller capabilities.

Selection Notes

Select this component when nonvolatile storage is required for calibration data or user settings. The 100 kOhm resistance value suits moderate impedance applications. Verify that the 32-tap resolution meets the precision requirements of the target circuit design.

Part Context

This part belongs to the MAX5475 series of digital potentiometers. It serves as a solid-state replacement for mechanical potentiometers in space-constrained designs requiring programmable resistance adjustments.

Replacement Considerations

Check for pin-compatible alternatives within the same series if different packaging options are needed. Verify interface protocol compatibility before substituting with other digital potentiometer models.
