MAX5433LETA+T

Overview

The MAX5433LETA+T is a nonvolatile, linear-taper digital potentiometer featuring 32 tap points and a 100kΩ end-to-end resistance. It utilizes a fast-mode I²C-compatible serial interface for control. The device includes internal EEPROM to recall the wiper position at power-up. Operating on a single supply from +2.7V to +5.25V, it draws typically 0.5µA in standby. Key electrical parameters include a 35ppm/°C temperature coefficient, ±0.15 LSB typical INL/DNL, and a 250kHz bandwidth. It is housed in an 8-pin TDFN package with an exposed pad.

Feature Summary

Nonvolatile memory retains wiper position across power cycles
I²C-compatible serial interface supports up to 400kbps data rates
Low standby current consumption of 0.5µA (typical)
Linear taper with 32 discrete tap positions

Applications

Mechanical potentiometer replacement
Low-drift programmable-gain amplifier circuits
Liquid-crystal display (LCD) screen adjustment
Volume control systems

Procurement Notes

Verify the specific ordering suffix 'LETA' corresponds to the 8-pin TDFN package and the factory-set I²C address code '010100A'. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the design accounts for the exposed thermal pad connection requirements specified in the package outline drawings.

Selection Notes

Select this component when a 100kΩ resistance value is required; the MAX5432 variant provides 50kΩ. The 'L' suffix indicates a specific factory-programmed I²C slave address. Verify that the system bus voltage levels are compatible with the +2.7V to +5.25V operating range. Consider the 3mm x 3mm TDFN package dimensions for PCB layout constraints.

Part Context

This part belongs to the MAX5432–MAX5435 family of 32-tap nonvolatile digital potentiometers. The MAX5433 specifically denotes the 100kΩ resistance version within the TDFN package lineup. The 'E' indicates the TDFN-EP package type, while 'T' signifies tape-and-reel packaging. These devices replace mechanical pots in space-constrained designs.
