X9116WM8ZT1

Digital Potentiometers Overview

The X9116WM8ZT1 is a digitally controlled potentiometer (XDCP) from the X9116 series, manufactured by Renesas Electronics. It features a single potentiometer with 16 taps and a total resistance of 10 kOhms. The device utilizes a nonvolatile memory architecture to store wiper positions, which are recalled upon power-up. It operates on a 5 V supply voltage with a maximum active current of 150 uA. The component is housed in an 8-MSOP surface-mount package and supports a linear taper. It is designed for applications requiring variable resistance without mechanical trimmers.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position data across power cycles
• 3-wire serial interface (U/D, INC, CS) for tap control
• 16 programmable wiper taps with linear taper
• Low power consumption: 150 uA active, 5 uA standby

Digital Potentiometers Applications

• Replacing mechanical trimmers in circuit trimming applications
• Programmable gain adjustment in signal processing circuits
• Offset voltage error trimming in amplifier circuits
• Volume control in audio circuits

Digital Potentiometers Procurement Notes

The X9116WM8ZT1 is classified as obsolete and no longer manufactured. Verification of availability should focus on surplus or secondary market sources, as original distribution channels have discontinued production. Check datasheets for End-of-Life notices and potential alternative part numbers from the same manufacturer family.

Digital Potentiometers Selection Notes

Select this component only if legacy compatibility with the X9116 series is required. Ensure the design accommodates the 8-MSOP package dimensions and the specific 10 kOhm resistance value. Verify that the 3-wire serial interface timing requirements align with the host microcontroller's capabilities.

Digital Potentiometers Part Context

This part belongs to the Intersil/Renesas X9116 family of solid-state nonvolatile digital potentiometers. It serves as a direct replacement for mechanical potentiometers in space-constrained designs. The 'T1' suffix indicates tape and reel packaging, while 'WM8Z' denotes the MSOP-8 package and lead-free composition.

Digital Potentiometers Replacement Considerations

Direct replacements may be limited due to the obsolete status. Consider evaluating other parts within the X9116 family or newer Renesas digital potentiometer series that offer compatible pinouts and electrical specifications.
