X9116WS8IZ

Digital Potentiometers Overview

The X9116WS8IZ is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a single potentiometer circuit with 16 wiper taps and a total resistance of 10 kOhms. The device utilizes a serial up/down interface for tap position control and includes nonvolatile memory to retain the last wiper setting upon power-up. It operates within a supply voltage range of 2.7 V to 5.5 V, with typical operating voltages at 3.3 V and 5 V. The component is housed in an 8-SOIC surface-mount package and supports an industrial temperature range from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Solid-state nonvolatile design with 16 programmable wiper taps
• 3-wire up/down serial interface for tap position adjustment
• Nonvolatile memory retains wiper position after power loss
• Low active current consumption of 50 µA maximum

Digital Potentiometers Applications

• Trimmer applications replacing mechanical potentiometers
• Variable resistance circuits requiring digital control
• Systems needing temperature and time stability over mechanical components

Digital Potentiometers Procurement Notes

The X9116WS8IZ is classified as obsolete and end-of-life by the manufacturer. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturing channels. Buyers must confirm the specific revision and packaging condition when sourcing from third-party vendors due to the discontinuation status.

Digital Potentiometers Selection Notes

Select this component only if legacy compatibility with the Intersil X9116 series is required. Ensure the application can accommodate the 8-SOIC package dimensions and the specific 3-wire serial interface timing. Verify that the 10 kOhm resistance value and 16-tap resolution meet the circuit requirements before considering alternative digital potentiometers.

Digital Potentiometers Part Context

This part belongs to the X9116 family of digitally controlled potentiometers originally developed by Intersil and later acquired by Renesas Electronics. The X9116 series was designed to provide solid-state alternatives to mechanical trimmers, offering improved reliability and stability. The WS8 suffix indicates the SOIC-8 package variant within this product line.

Digital Potentiometers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component is obsolete, engineers should evaluate modern digital potentiometer families from Renesas or other manufacturers that offer compatible interfaces and pinouts.
