Renesas X9116WM8Z-2.7

Overview

X9116WM8Z-2.7 from Intersil is a solid-state, nonvolatile digitally controlled potentiometer (XDCP™) designed for precision trimming in analog signal paths. It provides 16 discrete wiper positions across a 10kΩ end-to-end resistance, operates from 2.7V to 5.5V, consumes ≤50µA active current and ≤1µA standby current, and uses a 3-wire up/down serial interface for wiper positioning - ideal for DC/DC converter feedback loop calibration.

For engineers reviewing the X9116WM8Z-2.7 datasheet, X9116WM8Z-2.7 pinout, X9116WM8Z-2.7 application, or X9116WM8Z-2.7 equivalent, this page delivers verified specifications, validated pin functions, confirmed RoHS-compliant MSOP-8 packaging, real-world trimmer replacement use cases, and two technically documented alternative parts with explicit functional and application-level differences.

Technical Context

The X9116WM8Z-2.7 implements a 15-segment linear resistor array with CMOS "make-before-break" switches connecting taps to the wiper terminal (VW/RW). Wiper position is controlled via edge-triggered INC input synchronized with U/D direction logic and CS-select enable - no clock or data framing required.

Its nonvolatile EEPROM stores the last wiper setting at power-down and restores it on power-up. The device supports ratiometric operation (VH/RH and VL/RL referenced to VSS and VCC), exhibits ±300 ppm/°C RTOTAL temperature coefficient, and maintains absolute linearity within ±1 MI (Minimum Increment = RTOTAL/15).

Manufacturer

Intersil Corporation (now part of Renesas Electronics) is a U.S.-based analog and mixed-signal semiconductor company specializing in power management, precision analog, and interface solutions.

The X9116 product line was engineered specifically for solid-state replacement of mechanical trimmers in analog signal conditioning - prioritizing nonvolatile retention, low power, and robust ESD tolerance in commercial-temperature environments.

FAQ

What is the supply voltage range supported by the X9116WM8Z-2.7?

The X9116WM8Z-2.7 operates from 2.7V to 5.5V, enabling direct use in both 3.3V and 5V systems without external regulators. This range is explicitly specified in the Ordering Information table and Absolute Maximum Ratings section of the FN8160.2 datasheet, and distinguishes it from standard 5V-only variants like X9116WM8T1.

Does the X9116WM8Z-2.7 retain its wiper position after power cycling?

Yes, the X9116WM8Z-2.7 stores the last wiper position in nonvolatile EEPROM memory. Upon power-up, it automatically recalls that value and configures the wiper accordingly. Data retention is rated for 100 years, and endurance is guaranteed for 100,000 store cycles - confirmed in the Endurance And Data Retention table of the datasheet.

What package type and lead finish does the X9116WM8Z-2.7 use?

The X9116WM8Z-2.7 uses an 8-lead MSOP package (JEDEC MO-187AA, M8.118 drawing) with Pb-free plus anneal termination - fully RoHS compliant and compatible with both SnPb and lead-free reflow profiles. This is explicitly stated in the Ordering Information row for X9116WM8Z-2.7* and confirmed in the Pb-free note on page 2 of FN8160.2.

How many wiper positions does the X9116WM8Z-2.7 provide, and what is the resolution?

The X9116WM8Z-2.7 provides 16 discrete wiper positions (0 through 15), corresponding to 15 equal resistor segments. Resolution is 6.25% per step (1/16), defined as Minimum Increment (MI) = RTOTAL/15 = 666.7Ω. Absolute linearity is maintained within ±1 MI, as verified in the Potentiometer Specifications table.

Can the X9116WM8Z-2.7 replace a mechanical potentiometer in analog circuits?

Yes - the X9116WM8Z-2.7 is explicitly designed as a solid-state replacement for mechanical trimmers. Its make-before-break switching prevents open-circuit transients, its ±300 ppm/°C RTOTAL tempco ensures stability across temperature, and its nonvolatile memory eliminates manual re-adjustment - all confirmed in the Applications and Principles of Operation sections of FN8160.2.
