Product details
Overview
X9116WS8IZ from Intersil is a solid-state, nonvolatile digitally controlled potentiometer (XDCP™) designed for precision trimmer replacement in analog feedback and calibration circuits. It features 16 wiper taps across a 10kΩ linear resistor array, 3-wire up/down serial interface, 2.7V–5.5V supply operation, and <1µA standby current. Used in DC/DC converter voltage trimming, sensor offset adjustment, and programmable gain control.
For engineers reviewing the X9116WS8IZ datasheet, X9116WS8IZ pinout, X9116WS8IZ application, or X9116WS8IZ equivalent, this page delivers verified specifications, real-world use cases, pin-level design meaning, and validated alternative options - all grounded in the official FN8160.2 datasheet and Intersil ordering documentation.
Technical Context
The X9116WS8IZ implements a 4-bit counter-driven decoder controlling 15 equal resistor segments and CMOS "make-before-break" switches to select one of 16 wiper positions. Its nonvolatile EEPROM stores the last wiper setting, recalled automatically at power-up.
Wiper movement is edge-triggered: a falling edge on INC (active-low) increments or decrements position based on U/D pin state. Storage occurs only when CS transitions HIGH while INC is HIGH - enabling volatile runtime adjustment without overwriting stored defaults.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 10kΩ end-to-end resistance - defines full-scale analog range for voltage divider or variable resistor configurations. |
| VCC Range | 2.7V to 5.5V - supports single-supply operation across industrial and commercial systems without level-shifting. |
| Wiper Resolution | 16 taps (15 segments) - provides ~6.25% step resolution per tap; minimum increment = 667Ω at 10kΩ. |
| Standby Current | <1µA - enables battery-powered or ultra-low-power systems to retain trim settings indefinitely with negligible drain. |
| Nonvolatile Endurance | 100,000 write cycles - ensures long-term reliability in field-adjustable calibration applications. |
| Temperature Coefficient | ±300 ppm/°C (RTOTAL), ±20 ppm/°C (ratiometric) - guarantees stable resistance ratio over -40°C to +85°C operating range. |
| Wiper Resistance | 400Ω to 1000Ω at 2.7V - impacts loading error in high-impedance voltage divider designs; must be factored into accuracy budgets. |
Pinout & Package
Package: 8-lead SOIC (M8.15), RoHS-compliant Pb-free plus anneal finish, moisture sensitivity level (MSL) 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VH/RH | High-side fixed terminal | Connects to maximum potential (e.g., VCC or reference voltage); forms top node of voltage divider. |
| VSS | Ground reference | System ground return; required for proper logic-level interpretation and internal switch biasing. |
| INC | Increment control input | Negative-edge-triggered; initiates wiper movement when CS is LOW - timing-critical for reliable tap stepping. |
| U/D | Direction control input | Logic level (HIGH/LOW) sets wiper move direction on next INC edge - enables bidirectional fine-tuning. |
| CS | Chip select input | Active-low enable; storage to nonvolatile memory occurs only on HIGH transition while INC = HIGH. |
| VL/RL | Low-side fixed terminal | Connects to minimum potential (e.g., VSS or signal return); forms bottom node of voltage divider. |
| VW/RW | Wiper output terminal | Provides adjustable voltage/resistance point; series resistance (400–1000Ω @ 2.7V) affects loading and bandwidth. |
| VCC | Supply voltage | Power source for logic and analog array; must exceed VH/VL/VW potentials to prevent latch-up per absolute max ratings. |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state nonvolatile memory | Retains last wiper position across power cycles without external backup - eliminates mechanical drift and manual recalibration. |
| 3-wire up/down serial interface | Requires only three GPIOs (CS, INC, U/D) - simplifies integration into microcontroller-based systems without SPI/I²C peripherals. |
| Make-before-break wiper switching | Prevents open-circuit transients during tap changes - critical for stable operation in feedback loops and audio paths. |
| Low power consumption | Active current <150µA typ., standby <1µA - suitable for always-on sensor nodes and energy-harvesting applications. |
| Industrial temperature range | -40°C to +85°C operation - qualified for automotive body electronics, industrial PLC modules, and outdoor instrumentation. |

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, 5ppm/°C tempco | Higher resolution and lower tempco, but requires I²C bus and lacks up/down simplicity | Choose for precision calibration where microcontroller has I²C and finer adjustment is needed. |
| MCP4017T-103 | Up/down interface, 64-tap, 10kΩ, 1.8–5.5V, 1µA standby, no nonvolatile memory | Same 3-wire protocol but volatile-only storage - requires external MCU to reprogram at boot | Choose when cost is critical and system firmware can manage wiper initialization on every power cycle. |
Compared with AD5171BRMZ-10 and MCP4017T-103, the X9116WS8IZ uniquely balances low-pin-count up/down control, true nonvolatility, industrial temperature rating, and sub-1µA standby - making it optimal for self-contained, maintenance-free trim applications without host processor dependency.

FAQ
What is the operating temperature range for the X9116WS8IZ?
The X9116WS8IZ is rated for industrial operation from -40°C to +85°C. This specification is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the FN8160.2 datasheet. The device maintains full functionality-including nonvolatile storage, wiper movement, and resistance stability-across this full range, making it suitable for under-hood automotive modules and industrial control cabinets.
Does the X9116WS8IZ require an external clock or microcontroller to function?
No, the X9116WS8IZ operates autonomously using only three digital control signals: CS, INC, and U/D. It contains an internal counter and decoder, requiring no external clock source or firmware. A microcontroller is optional for automation but not mandatory - simple pushbutton debounced inputs can directly drive the X9116WS8IZ for manual field adjustment.
How is nonvolatile storage triggered on the X9116WS8IZ?
Nonvolatile storage on the X9116WS8IZ occurs only when two simultaneous conditions are met: CS transitions from LOW to HIGH *and* INC is held HIGH at that moment. This precise timing requirement prevents accidental writes during normal operation. Once stored, the wiper position persists through power cycles and is automatically restored at next power-up.
What is the maximum allowable voltage between VH and VL terminals on the X9116WS8IZ?
The absolute maximum voltage difference between VH/RH and VL/RL is 5.5V, as specified in the Absolute Maximum Ratings table. This limit applies regardless of VCC level. Exceeding ΔV = |VH − VL| > 5.5V risks permanent damage to the internal resistor array and CMOS switches - a critical constraint when using the X9116WS8IZ in high-voltage sensor interfaces or motor control feedback networks.
Can the X9116WS8IZ be used in a two-terminal variable resistor configuration?
Yes, the X9116WS8IZ supports two-terminal operation by connecting either VH/RH or VL/RL to a fixed potential and using VW/RW with the remaining terminal. In this mode, it functions as a digitally adjustable rheostat. The datasheet confirms this in "Basic Configurations" (page 7), noting that wiper resistance (400–1000Ω at 2.7V) and current limits (±1mA) must be respected to avoid exceeding power dissipation or degrading linearity.
