X9315UMI-2.7

Digital Potentiometers Overview

The X9315UMI-2.7 is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation, part of the X9315 series. It features a single potentiometer circuit with 32 taps and a resistance value of 50 kOhms. The device utilizes a linear taper and operates on a supply voltage ranging from 2.7 V to 5.5 V. It employs an Increment/Decrement control interface (U/D, INC, CS) and includes nonvolatile memory to retain wiper position settings across power cycles. The component is housed in an 8-MSOP surface-mount package.

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors as counterfeits exist. Confirm RoHS compliance status for specific manufacturing lots. Check moisture sensitivity level (MSL) handling requirements prior to PCB assembly. Validate pinout compatibility with target footprint design.

Digital Potentiometers Selection Notes

Select this model for applications requiring precise resistance adjustment without mechanical wear. Ensure supply voltage stays within 2.7V to 5.5V range. Consider the 50kOhm nominal resistance and 200 Ohm contact resistance for signal integrity. Verify thermal performance within the specified operating temperature range.

Digital Potentiometers Part Context

This component belongs to the X9315 family of low-noise, low-power digitally controlled potentiometers. It serves as a solid-state alternative to traditional mechanical potentiometers, offering improved reliability and programmability in compact electronic designs.

Digital Potentiometers Replacement Considerations

Direct replacements include other X9315 variants with different resistance values or packages, such as X9315WSZ-2.7 (10kOhm, SOIC-8) or X9315TMIZ-2.7T2 (100kOhm, MSOP-8). Ensure interface compatibility and electrical specifications match before substitution.
