X9315WMIZ-2.7R5419

Digital Potentiometers Overview

The X9315WMIZ-2.7R5419 is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation, belonging to the X9315 series. It features a single potentiometer circuit with 32 taps and a resistance value of 10 kOhms. The device utilizes a linear taper and incorporates nonvolatile memory to retain wiper position settings. Control is managed via a serial 3-wire interface consisting of CS, U/D, and INC inputs. It operates within a supply voltage range of 2.7 V to 5.5 V and is housed in an 8-MSOP package.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position upon power loss
• 3-wire serial control interface (CS, U/D, INC)
• Single pot configuration with 32 resistive taps
• Linear taper characteristic

Digital Potentiometers Applications

• Audio volume control circuits
• Programmable gain amplifier adjustments
• Voltage reference trimming
• Sensor calibration systems

Digital Potentiometers Procurement Notes

Verify the specific suffix R5419 against official Renesas documentation to confirm packaging details and compliance status. Ensure compatibility with existing PCB footprints for the MSOP-8 package. Check current lifecycle status as some X9315 variants are discontinued.

Digital Potentiometers Selection Notes

Select this component when a low-power, nonvolatile digital potentiometer with 10 kOhm resistance is required. The 3-wire interface minimizes GPIO usage compared to I2C/SPI alternatives. Verify that the 32-tap resolution meets the application's adjustment precision requirements.

Digital Potentiometers Part Context

This part is part of the Intersil/Renesas X9315 family of low-noise, low-power digitally controlled potentiometers. The family offers various resistance values (10k, 50k, 100k) and packages (SOIC, MSOP). The X9315 series is known for its simple incremental/decremental control scheme.

Digital Potentiometers Replacement Considerations

Direct pin-to-pin replacements include other X9315 variants with matching resistance and package, such as X9315WMIZ or X9315WSIZ, provided the resistance value and interface logic are compatible.
