X9315WMI-2.7T2

Digital Potentiometers Overview

The X9315WMI-2.7T2 is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation, part of the XDCP series. It features a single potentiometer circuit with 32 taps and a resistance value of 10 kOhms. The device utilizes nonvolatile memory to retain wiper position settings across power cycles. Control is managed via an Increment/Decrement interface using CS, U/D, and INC inputs. It operates within a supply voltage range of 2.7V to 5.5V and is housed in an 8-MSOP package.

Digital Potentiometers Feature Summary

• Nonvolatile Memory: Stores wiper position data for recall upon power-up.
• 3-Wire Interface: Controlled via CS, U/D, and INC pins for increment/decrement operations.
• Single Circuit Configuration: Contains one potentiometer with 32 adjustable taps.
• Low Power Operation: Designed for low noise and low power consumption applications.

Digital Potentiometers Applications

• Audio volume control
• Gain adjustment in instrumentation circuits
• Voltage reference trimming
• System calibration

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized Renesas distributors or direct manufacturer channels. Confirm RoHS compliance status and specific packaging details such as tape and reel quantities against current datasheets. Check for obsolescence notices or product change notifications (PCN) prior to procurement.

Digital Potentiometers Selection Notes

Select this component when a 10 kOhm digital potentiometer with nonvolatile storage is required. Ensure the application voltage falls within the 2.7V to 5.5V range. Verify that the MSOP-8 package fits the PCB layout constraints and that the 3-wire serial interface is compatible with the system controller.

Digital Potentiometers Part Context

This component belongs to the X9315 family of digitally controlled potentiometers from Renesas (formerly Intersil). The 'W' suffix typically denotes a 10 kOhm resistance value, while 'MIZ' indicates the MSOP-8 package type. The 'T2' suffix often refers to the specific tape and reel packaging configuration.

Digital Potentiometers Replacement Considerations

Direct substitutes may include other models within the X9315 family with matching resistance values and packages, such as X9315WMIZ variants. Cross-reference pinouts and electrical specifications carefully before substitution.
