MAX5161MEZT+T

Overview

The MAX5161MEZT+T is a low-power, linear-taper digital potentiometer manufactured by Analog Devices Inc./Maxim Integrated. It provides 32 tap positions with resistance values of 50kΩ, 100kΩ, or 200kΩ. The device operates on a single supply voltage ranging from +2.7V to +5.5V and draws only 100nA of supply current. It features ±1LSB DNL, ±0.5LSB INL, and a nominal end-to-end temperature coefficient of 50ppm/°C. Packaged in a compact 6-pin SOT23 format, it includes power-on reset functionality that sets the wiper to midscale upon initialization.

Feature Summary

• 32 Tap Positions with 50kΩ, 100kΩ, and 200kΩ Resistance Options
• Low Power Consumption: 100nA Supply Current at +2.7V to +5.5V
• High Linearity: ±1LSB DNL and ±0.5LSB INL
• Glitchless Switching Between Resistor Taps

Applications

• LCD Screen Adjustment
• Volume Control
• Mechanical Potentiometer Replacement

Procurement Notes

Verify component authenticity through authorized distributors. Confirm package integrity for the 6-pin SOT23 form factor. Check RoHS compliance status as indicated in official documentation. Ensure storage conditions remain within specified limits to maintain reliability.

Selection Notes

Select the MAX5161MEZT+T when a small-footprint variable resistor is required. Choose this model over the MAX5160 if a 6-pin package is preferred. Verify that the specific resistance value (50kΩ, 100kΩ, or 200kΩ) matches circuit requirements before procurement.

Part Context

This component belongs to the MAX5160/MAX5161 family of low-power digital potentiometers. The MAX5161 variant specifically utilizes a 6-pin SOT23 package and integrates the Chip Select (CS) pin internally to ground, functioning as a two-terminal variable resistor.
