MAX5161LEZT+T

Overview

The MAX5161LEZT+T is a low-power digital potentiometer featuring 32 tap positions and available in a 6-pin SOT-23 package. It operates on a single supply voltage ranging from +2.7V to +5.5V with a typical supply current of 100nA. The device provides three resistance values: 50kΩ, 100kΩ, and 200kΩ, with a nominal end-to-end temperature coefficient of 50ppm/°C and a ratiometric coefficient of 5ppm/°C. Key electrical characteristics include ±1LSB differential nonlinearity (DNL), ±0.5LSB integral nonlinearity (INL), and a wiper resistance of 400Ω. It includes power-on reset functionality that sets the wiper to midscale upon initialization.

Feature Summary

32 Tap Positions with Glitchless Switching
Low Power Consumption (100nA Supply Current)
±1LSB DNL and ±0.5LSB INL Linearity
Single-Supply Operation (+2.7V to +5.5V)

Applications

LCD Screen Adjustment
Volume Control
Mechanical Potentiometer Replacement

Procurement Notes

Verify the component authenticity by checking for the 'LE' suffix which indicates the 50kΩ resistance value and the '+T' designation for tape-and-reel packaging. Confirm the manufacturer details match Analog Devices or Maxim Integrated specifications. Ensure the operating environment stays within the specified -40°C to +85°C temperature range to maintain guaranteed performance parameters.

Selection Notes

Select the MAX5161LEZT+T when a compact 6-pin SOT-23 form factor is required compared to the 8-pin µMAX MAX5160 variant. Choose this specific part for applications needing a 50kΩ resistance value; other resistance options require different ordering suffixes. Consider its low power consumption and small footprint for battery-operated or space-constrained designs requiring digitally adjustable resistance.

Part Context

The MAX5161 is part of the MAX5160/MAX5161 family of low-power digital potentiometers. While the MAX5160 offers an 8-pin configuration with separate H and L terminals, the MAX5161 utilizes a 6-pin SOT-23 package where the wiper terminal is internally shorted to the high terminal, functioning as a variable resistor. Both devices share identical control logic and electrical performance characteristics.
