MAX5386MATE+T

Overview

The MAX5386MATE+T is a dual, volatile, low-voltage linear taper digital potentiometer manufactured by Analog Devices Inc./Maxim Integrated. It features two independent 256-tap potentiometers with an end-to-end resistance of 50kΩ and a tolerance of ±25%. Operating from a single +2.6V to +5.5V supply, it draws a standby current of 1µA. The device utilizes a 3-wire SPI interface for wiper control and operates within an extended temperature range of -40°C to +125°C. It is housed in a 16-pin TQFN-EP package.

Feature Summary

• Dual 256-Tap Linear Taper Digital Potentiometers

• Low Quiescent Supply Current (< 1µA)
• Extended Temperature Range (-40°C to +125°C)

Applications

• Low-Voltage Battery Applications
• Portable Electronics
• Mechanical Potentiometer Replacement
• Offset and Gain Control

Procurement Notes

Verify the specific ordering suffix '+T' indicates tape-and-reel packaging when sourcing this component. Confirm that the 'M' designation corresponds to the 50kΩ resistance value. Ensure compatibility with the 16-pin TQFN-EP footprint during procurement planning.

Selection Notes

Select the MAX5386MATE+T specifically for applications requiring a 50kΩ end-to-end resistance. Verify that the volatile memory characteristic aligns with system power-loss requirements. Ensure the host controller supports the required 3-wire SPI protocol for proper configuration.

Part Context

This part belongs to the MAX5386 family of dual digital potentiometers. The 'M' suffix specifies the 50kΩ resistance variant, while 'ATE' denotes the 16-pin TQFN-EP package. The '+' suffix indicates lead-free/RoHS compliance. The 'T' suffix typically signifies reel packaging.

Replacement Considerations

The MAX5386LATE+ (10kΩ) and MAX5386NATE+ (100kΩ) are direct pin-compatible alternatives within the same package offering different resistance values.
