X9116WS8IZT1

Digital Potentiometers Overview

The X9116WS8IZT1 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 during power-off, recalling it upon power-up. It operates on a 5V supply voltage with a maximum active current of 150 uA. The component is housed in an 8-lead SOIC package and supports a serial 3-wire interface for control.

Digital Potentiometers Feature Summary

• Solid-state nonvolatile 16 wiper taps
• 3-wire up/down serial interface
• Active current 150 uA max at 5V
• Linear taper with 10 kOhm resistance

Digital Potentiometers Applications

• Trimmer applications replacing mechanical potentiometers
• Variable resistance circuits requiring temperature stability
• Parameter adjustment in signal processing

Digital Potentiometers Procurement Notes

The X9116WS8IZT1 is listed as obsolete and end-of-life by the manufacturer. Verification of availability should focus on secondary market distributors or surplus stock providers. Ensure that any sourced units are RoHS compliant and verify the specific packaging type against project requirements.

Digital Potentiometers Selection Notes

Select this component for applications requiring a simple 3-wire interface and nonvolatile storage of a single resistance value. The 10 kOhm range and 16-tap resolution suit low-precision trimming tasks. Consider the SOIC-8 package dimensions and the -40°C to +85°C operating temperature range for environmental compatibility.

Digital Potentiometers Part Context

This part belongs to the X9116 series of digitally controlled potentiometers from Intersil, now part of Renesas. The suffix 'WS8' indicates the SOIC-8 package, 'I' denotes the industrial temperature range, and 'ZT1' specifies the tape and reel packaging format with 2500 units per reel.

Digital Potentiometers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the product is obsolete, engineers must evaluate alternative digital potentiometers with similar interface protocols and resistance values.
