Product details
Overview
X9116WM8Z from Intersil is a solid-state, nonvolatile digitally controlled potentiometer (XDCP™) designed for precision trimmer replacement in analog signal conditioning and power supply feedback loops. It provides 16 discrete wiper positions across a 10kΩ end-to-end resistance, operates from 2.7V to 5.5V, draws ≤50µA active current and ≤1µA standby current, and retains wiper position in EEPROM after power cycling.
For engineers reviewing the X9116WM8Z datasheet, X9116WM8Z pinout, X9116WM8Z application, or X9116WM8Z equivalent, this device serves as a drop-in upgrade for mechanical trimmers where long-term stability, temperature drift immunity, and programmable recalibration are required - especially in DC/DC converter voltage setpoints, sensor offset calibration, and audio gain control circuits.
Technical Context
The X9116WM8Z implements a 4-bit up/down counter driving a 15-segment linear resistor array with CMOS "make-before-break" switches, enabling glitch-free wiper transitions. Its 3-wire serial interface (U/D, INC, CS) uses edge-triggered logic: a falling edge on INC increments or decrements the wiper position based on U/D logic level, while CS high with INC high initiates nonvolatile store.
Wiper position is retained in EEPROM with 100,000 write cycles and 100-year data retention. The device supports ratiometric operation (VW = VSS + (n/15) × (VH − VL)), exhibits ±1 MI absolute linearity and ±0.2 MI relative linearity, and maintains ±300 ppm/°C RTOTAL temperature coefficient over 0°C to +70°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 10kΩ end-to-end resistance; defines maximum adjustable range in voltage divider or variable resistor configurations. |
| Wiper Positions | 16 discrete taps (0–15); enables 6.25% resolution per step in linear taper applications. |
| VCC Range | 2.7V to 5.5V; supports single-supply operation across legacy 3.3V and 5V systems without level shifting. |
| Active Current | <50µA max; minimizes system power budget impact during dynamic adjustment. |
| Standby Current | <1µA max; enables battery-powered or always-on calibration circuits with negligible quiescent drain. |
| Nonvolatile Store Time | 5–10ms; ensures reliable EEPROM write before power loss or host controller timeout. |
| Wiper Resistance | 200–400Ω at 5V; limits loading error when used as a low-impedance voltage source or current-sense node. |
Pinout & Package
Package: 8-lead MSOP (Moisture Sensitivity Level 2, Pb-free plus anneal, RoHS compliant), dimensions per JEDEC MO-187AA (M8.118).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VH/RH | High terminal | Fixed end of resistor array; connects to highest potential (up to VCC) in voltage divider mode. |
| VL/RL | Low terminal | Fixed end of resistor array; connects to lowest potential (typically VSS) in voltage divider mode. |
| VW/RW | Wiper terminal | Movable tap output; delivers interpolated voltage between VH and VL; series resistance 200–400Ω affects load regulation. |
| VCC | Supply voltage | Power input (2.7–5.5V); must be ≥ VH, VL, VW at all times per power-up/down requirements. |
| VSS | Ground | Reference return path for internal logic and resistor array; must be common with system ground. |
| U/D | Up/down direction control | Static logic level (HIGH = increment, LOW = decrement) sampled on each INC falling edge. |
| INC | Increment clock input | Negative-edge-triggered; controls wiper movement timing and initiates store when CS rises with INC HIGH. |
| CS | Chip select | Active-low enable; device responds only when CS = LOW; rising edge with INC = HIGH triggers EEPROM store. |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state nonvolatile memory | 100-year data retention and 100,000-cycle endurance eliminate mechanical wear and enable factory-trimmed calibration persistence. |
| Make-before-break wiper switching | Prevents open-circuit glitches during tap transitions, critical for stable feedback in closed-loop power supplies. |
| Ratiometric voltage division | Output voltage scales linearly with supply (VW = VSS + (n/15)(VH − VL)), removing VCC dependency in sensor biasing. |
| Low-power serial interface | 3-wire protocol requires no clock generation or address decoding - compatible with GPIO-only microcontrollers. |
| Temperature-stable resistance | ±300 ppm/°C RTOTAL drift ensures <±0.5% total resistance change over 0°C to +70°C operating range. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5171BRMZ-10 | I²C interface, 64-tap resolution, 10kΩ, 2.7–5.5V, 5µA standby; no up/down serial mode. | Requires I²C master; better resolution but higher standby current; no direct GPIO compatibility. | Select when I²C infrastructure exists and finer adjustment granularity is needed over simple up/down control. |
| MCP4017T-103I/P | 6-bit up/down interface, 10kΩ, 2.7–5.5V, 0.5µA standby; volatile memory (no EEPROM). | Loses setting on power loss; requires host MCU to reinitialize wiper at boot; lower cost. | Select for cost-sensitive, non-critical trim applications where recalibration at startup is acceptable. |
Compared with AD5171BRMZ-10 and MCP4017T-103I/P, the X9116WM8Z uniquely balances GPIO-friendly 3-wire control, nonvolatile retention, ultra-low standby current, and industrial-grade temperature stability - making it optimal for unattended, maintenance-free analog trimming where power loss resilience is mandatory.

FAQ
What is the operating temperature range for the X9116WM8Z?
The X9116WM8Z is rated for commercial temperature operation from 0°C to +70°C, as confirmed in the ordering information table and absolute maximum ratings section of the FN8160.2 datasheet. This range applies to all X9116WM8Z variants, including the Pb-free M8.118 MSOP package.
Does the X9116WM8Z require external pull-up resistors on its control pins?
No, the X9116WM8Z does not require external pull-ups on U/D, INC, or CS. Its input leakage current is ±10µA, and VIH/VIL thresholds (2.0V min HIGH, 0.8V max LOW) are compatible with standard CMOS logic levels. Internal weak pull-downs are not specified, so host MCU GPIOs must drive defined logic states.
How is nonvolatile storage triggered on the X9116WM8Z?
Nonvolatile storage on the X9116WM8Z occurs when CS transitions from LOW to HIGH while the INC pin is held HIGH. This specific timing condition initiates an internal EEPROM write cycle lasting 5–10ms, after which the device enters standby mode. The stored wiper position is automatically recalled at next power-up.
Can the X9116WM8Z be used in a two-terminal variable resistor configuration?
Yes, the X9116WM8Z supports two-terminal operation: connect VH/RH and VL/RL to fixed potentials (e.g., VCC and GND), then use VW/RW and one fixed terminal (e.g., VL/RL) as the variable resistance pair. The datasheet confirms this in "Basic Configurations" (page 7) and specifies ±1mA wiper current rating for such use.
What is the wiper resistance specification for the X9116WM8Z at 3.3V supply?
At VCC = 3.3V, the X9116WM8Z wiper resistance falls between 400Ω and 1000Ω, as specified in the "Potentiometer Specifications" table (page 4) under RW test conditions for VCC = 2.7V. Since 3.3V lies within the 2.7–5.5V range and RW decreases with increasing VCC, the 3.3V value is bounded by the 2.7V (400–1000Ω) and 5V (200–400Ω) limits.
