X9116WS8IZ-2.7T1

Digital Potentiometers Overview

The X9116WS8IZ-2.7T1 is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation, formerly Intersil. It features a single potentiometer with 16 taps and a total resistance of 10 kOhms. The device operates on a supply voltage ranging from 2.7 V to 5.5 V, with typical operating voltages at 3.3 V and 5 V. It utilizes a nonvolatile memory architecture to retain the wiper position upon power-up. The component employs a 3-wire serial interface for control and is housed in an 8-lead SOIC package.

Digital Potentiometers Feature Summary

• Solid-state nonvolatile design with 16 wiper taps
• 3-wire up/down serial interface for tap positioning
• Power-on recall of last stored wiper position
• Operates within 2.7 V to 5.5 V supply range

Digital Potentiometers Applications

• Trimmer applications replacing mechanical potentiometers
• Variable resistance circuits requiring digital control
• Parameter adjustment in electronic systems

Digital Potentiometers Procurement Notes

This component is classified as End of Life (EOL). Availability is limited to existing stock or surplus channels. Verification of RoHS compliance and specific manufacturing site origin is recommended due to potential product change notices affecting assembly locations.

Digital Potentiometers Selection Notes

Select this part for low-pin-count applications requiring nonvolatile digital adjustment. Ensure the system supports a 3-wire serial interface. Verify that the 10 kOhm resistance and 16-tap resolution meet the circuit requirements. Note that the device is obsolete; alternative components from the same family may require pinout or interface verification.

Digital Potentiometers Part Context

The X9116 belongs to the X9116 series of Single Digitally Controlled Potentiometers. This specific suffix indicates an SOIC-8 package with a -2.7V minimum supply rating and tape-and-reel packaging. The series is designed for CMOS technology and offers linear taper characteristics.

Digital Potentiometers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consider checking the broader X9116 family for similar interfaces or consulting manufacturer cross-reference tools for current alternatives.
