MAX5395MATA+T

Overview

The MAX5395MATA+T is a single-channel, 256-tap volatile digital potentiometer with linear taper. It offers end-to-end resistance values of 10kΩ, 50kΩ, and 100kΩ. The device operates on a single supply from 1.7V to 5.5V with an internal charge pump enabling terminal voltages up to 5.25V independent of VDD. It features an I²C serial interface, ultra-low quiescent current (<1µA in low-power mode), and ±1.0 LSB INL accuracy. Packaged in an 8-pin TDFN (2mm x 2mm) format, it supports an automotive temperature range of -40°C to +125°C.

Procurement Notes

Verify the specific suffix 'M' indicates the 50kΩ resistance variant when sourcing. Confirm RoHS compliance status via official documentation. Ensure the ordering code matches the required tape-and-reel packaging format for automated assembly processes.

Selection Notes

Select this component for applications requiring precise digital adjustment of resistance or voltage division. The 50kΩ value suits moderate impedance circuits. Verify that the I²C bus speed does not exceed 400kHz and that the ADDR0 pin is properly terminated to avoid address conflicts.

Part Context

This part belongs to the MAX5395 family of low-voltage digital potentiometers. The 'M' suffix specifies the 50kΩ end-to-end resistance configuration. The '+T' suffix denotes lead-free material and tape-and-reel packaging. It serves as a solid-state replacement for mechanical potentiometers in space-constrained designs.

Replacement Considerations

Direct replacements include other MAX5395 variants with different resistance values (e.g., MAX5395LATA+T for 10kΩ). Ensure the substitute maintains the same 256-tap resolution and I²C interface compatibility.
