MAX5401EKA

Overview

The MAX5401EKA is a 256-tap digitally controlled variable resistor housed in an 8-pin SOT23 package. It operates on a single supply voltage ranging from +2.7V to +5.5V with an ultra-low supply current of 0.1µA. The device features a low ratiometric temperature coefficient of 5ppm/°C and includes glitchless switching between resistor taps. A power-on reset function initializes the wiper to the midscale position (Position 128) upon startup, ensuring predictable initial states.

Feature Summary

256-tap resolution in miniature 8-pin SOT23 (3mm x 3mm) package
Ultra-low supply current of 0.1µA for battery-powered applications
Glitchless switching between resistor taps prevents signal transients
Power-on reset sets wiper to midscale (Position 128) automatically

Applications

Mechanical potentiometer replacement in space-constrained designs
Low-drift programmable gain amplifier (PGA) circuits
Adjustable voltage reference implementations

Selection Notes

Select the MAX5401EKA when a compact digital potentiometer with low drift is required. Verify that the application supports the 2.7V to 5.5V single-supply range and utilizes a 3-Wire SPI-compatible interface for control. Ensure the specific resistance value variant matches the circuit requirements.

Part Context

This component belongs to the MAX5400/MAX5401 family of SOT-PoT™ digitally controlled variable resistors. These devices are designed to replace mechanical potentiometers in applications where size, reliability, and precise digital control are critical. The EKA suffix denotes the specific SOT23-8 package configuration.
