X9116WM8Z-2.7T1

Digital Potentiometers Overview

The X9116WM8Z-2.7T1 is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation, formerly Intersil. It features a single potentiometer with 10 kΩ total resistance and 16 tap positions. The device utilizes a nonvolatile memory architecture to retain the wiper position during power-off, recalling it upon power-up. It operates on a supply voltage range of 2.7 V to 5.5 V with a maximum active current of 150 µA and standby current of 5 µA. The component is housed in an 8-lead MSOP package and supports a 3-wire serial interface for control.

Digital Potentiometers Feature Summary

• Solid-state nonvolatile 16 wiper taps with linear taper
• 3-wire up/down serial interface (U/D, INC, CS)
• Supply voltage range: 2.7 V to 5.5 V
• Low power consumption: 150 µA active, 5 µA standby

Digital Potentiometers Applications

• Trimmer applications replacing mechanical potentiometers
• Variable resistance circuits requiring programmable adjustment
• Parameter adjustments in electronic systems

Digital Potentiometers Procurement Notes

The X9116WM8Z-2.7T1 is listed as obsolete and end-of-life by the manufacturer. Availability is restricted, and verification of genuine stock from authorized distributors is required before procurement. Design-in should consider alternative components due to discontinuation status.

Digital Potentiometers Selection Notes

Select this component only if legacy compatibility with the X9116 series is required. Verify that the 10 kΩ resistance and 16-tap resolution meet circuit requirements. Ensure the 3-wire serial interface aligns with the system's microcontroller or control logic capabilities.

Digital Potentiometers Part Context

This part belongs to the X9116 family of single-channel digitally controlled potentiometers. It is distinct from higher-resolution variants like the X9111 (1024 taps) or other interfaces within the XDCP portfolio. The 'WM8Z' suffix indicates the MSOP-8 package and RoHS compliance.
