X9116WM8IZ

Digital Potentiometers Overview

The X9116WM8IZ is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a single potentiometer with 16 taps and a total resistance of 10 kOhms. The device utilizes a nonvolatile memory architecture to retain the wiper position upon power-up. Control is achieved via a 3-wire up/down serial interface. It operates within a supply voltage range of 4.5 V to 5.5 V, consuming a maximum active current of 150 uA. The component is housed in an 8-lead MSOP package and supports a linear taper configuration.

Digital Potentiometers Feature Summary

• Solid-state nonvolatile 16 wiper taps
• 3-wire up/down serial interface for tap positioning
• Power-on recall of last stored wiper position
• Linear taper with 10 kOhm end-to-end resistance

Digital Potentiometers Applications

• Trimmer applications replacing mechanical potentiometers
• Variable resistance circuits requiring temperature stability
• Parameter adjustment in solid-state solutions

Digital Potentiometers Procurement Notes

The X9116WM8IZ is classified as obsolete and no longer in production. Availability is restricted, and verification of stock status through authorized distributors is required before procurement planning. End-of-life notices confirm that manufacturing has ceased.

Digital Potentiometers Selection Notes

Select this component only if legacy compatibility with the Intersil/Renesas X9116 family is mandatory. Verify that the 10 kOhm resistance and 16-tap resolution meet circuit requirements. Ensure the design accommodates the MSOP-8 package dimensions and the specific 3-wire serial control logic.

Digital Potentiometers Part Context

This part belongs to the X9116 series of Digitally Controlled Potentiometers. It is functionally related to variants such as X9116WS8IZ (SOIC package) and X9116WM8IZ-2.7 (lower voltage variant). The manufacturer transitioned from Intersil to Renesas Electronics Corporation during the product lifecycle.

Digital Potentiometers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the component is obsolete, alternative sourcing requires identifying pin-compatible digital potentiometers with similar tap counts and interface protocols.
