X9116WS8IZ-2.7

Digital Potentiometers Overview

The X9116WS8IZ-2.7 is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation, formerly Intersil. It features a single potentiometer with 16 wiper taps and a total resistance of 10 kOhms. The device utilizes a nonvolatile memory architecture to retain the last wiper position upon power-up. It operates on a 3-wire serial interface for increment/decrement control and supports supply voltages ranging from 2.7 V to 5.5 V. The component is housed in an 8-lead SOIC package and is rated for operation between -40°C and +85°C.

Digital Potentiometers Feature Summary

• Solid-state nonvolatile 16 wiper taps with linear taper
• 3-wire up/down serial interface for tap positioning
• Operates at VCC = 2.7V and 5V with active current max 50µA
• Designed as a solid-state replacement for mechanical trimmers

Digital Potentiometers Applications

• Trimmer applications requiring variable resistance
• Circuits needing temperature and time stability over mechanical alternatives
• Systems requiring reliable solid-state resistance adjustment

Digital Potentiometers Procurement Notes

This component is classified as obsolete and end-of-life. Verification of availability should focus on surplus distributors or secondary market sources rather than standard manufacturing channels. Confirm RoHS compliance status and specific packaging details through supplier documentation prior to acquisition.

Digital Potentiometers Selection Notes

Select this part for applications requiring a 10kΩ digital potentiometer with nonvolatile storage and 3-wire serial control. Ensure the design accommodates the 8-SOIC package dimensions. Verify that the system voltage aligns with the 2.7V to 5.5V operating range and that the interface logic matches the U/D and INC pin requirements.

Digital Potentiometers Part Context

The X9116 belongs to the X9116 series of Digitally Controlled Potentiometers. This family includes variants with different packages such as MSOP and SOIC, and various resistance values. The WS8 suffix indicates the 8-lead SOIC package configuration.

Digital Potentiometers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided data. As the device is obsolete, alternative solutions require manual selection based on functional equivalence, specifically matching the 10kΩ resistance, 16 taps, nonvolatile memory, and 3-wire interface.
