Overview
The MAX5160MEUA+T is a low-power, linear-taper digital potentiometer in an 8-pin µMAX package. It provides 32 tap positions with end-to-end 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 ±25% resistance tolerance, a nominal temperature coefficient of 50ppm/°C, and glitchless switching between taps. The wiper position is controlled via a 3-wire serial interface (CS, INC, U/D).
Feature Summary
- 32 Tap Positions with Linear Taper
- Low Power Consumption: 100nA Supply Current
- Single-Supply Operation: +2.7V to +5.5V
- Glitchless Switching Between Resistor Taps
Applications
- LCD Screen Adjustment
- Volume Control
- Mechanical Potentiometer Replacement
Procurement Notes
Verify the specific resistance value associated with the MEUA suffix by consulting the manufacturer's ordering guide, as the base model supports multiple resistance options.
Selection Notes
Select this component for applications requiring digitally adjustable resistance with low power consumption. Ensure the required resistance value (50kΩ, 100kΩ, or 200kΩ) matches the specific suffix variant available.
Part Context
This part belongs to the MAX5160/MAX5161 family of low-power digital potentiometers. The MAX5160 variant uses an 8-pin µMAX package and includes separate H and L terminals, whereas the MAX5161 uses a 6-pin SOT23 package with the wiper shorted to the high terminal.
Replacement Considerations
Direct replacements within the same family include MAX5160NEUA (200kΩ) and MAX5160LEUA (50kΩ), provided the resistance value matches the design requirements.
FAQ
What is the wiper settling time for the MAX5160?
The typical wiper-settling time is 1µs.
Does the device retain its wiper position after power loss?
No, the wiper memory is volatile. However, it features a power-on reset circuit that sets the wiper to midscale (position 16) at power-up.
What is the ESD protection rating?
The device offers ±2kV ESD protection.
