Product details
Overview
X9116WM8IZ-2.7T1 from Intersil is a solid-state, nonvolatile digitally controlled potentiometer (XDCP™) designed for precision trimming in analog signal paths. It features 16 wiper taps across a 10kΩ linear resistor array, operates from 2.7V to 5.5V, consumes <1µA standby current, and retains wiper position in EEPROM after power cycling - enabling reliable recalibration in industrial sensor front-ends and DC/DC converter feedback loops.
For engineers reviewing the X9116WM8IZ-2.7T1 datasheet, X9116WM8IZ-2.7T1 pinout, X9116WM8IZ-2.7T1 application, or X9116WM8IZ-2.7T1 equivalent, this page delivers verified electrical specs, true pin functions, real-world use cases, and validated alternative parts - all grounded in the FN8160.2 datasheet and Intersil's official ordering documentation.
Technical Context
The X9116WM8IZ-2.7T1 implements a 4-bit up/down counter driving a 15-segment resistor ladder via CMOS switches with make-before-break switching behavior. Its 3-wire serial interface (U/D, INC, CS) enables deterministic tap positioning without clock or data lines - simplifying microcontroller GPIO usage while avoiding bus arbitration overhead.
Nonvolatile storage occurs only on CS↑ with INC held HIGH, ensuring intentional EEPROM writes; power-up restores the last stored wiper position, eliminating startup drift. The device supports ratiometric operation between VL/RL and VH/RH terminals, with wiper resistance varying from 400Ω to 1000Ω at 2.7V supply - critical for low-voltage bias network accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 10kΩ end-to-end resistance - defines full-scale adjustment range in voltage divider or variable resistor configurations |
| Wiper Taps | 16 discrete positions (0–15) - provides 6.25% resolution per step for fine analog tuning |
| VCC Range | 2.7V to 5.5V - supports direct integration into 3.3V and 5V systems without level-shifting |
| Standby Current | <1µA - enables always-on calibration retention in battery-powered instrumentation |
| Active Current | <50µA max - minimizes power impact during dynamic wiper adjustment |
| Wiper Resistance | 400Ω to 1000Ω at 2.7V - directly affects output impedance and loading in buffered reference circuits |
| Nonvolatile Endurance | 100,000 write cycles - ensures long-term reliability in field-updatable trim applications |
| Data Retention | 100 years - guarantees wiper setting persistence across product lifetime without refresh |
Pinout & Package
Package: 8-lead MSOP (Moisture Sensitivity Level 2, JEDEC MO-187AA compliant), Pb-free plus anneal (RoHS-compliant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VH/RH | High terminal of resistor array | Connects to maximum potential node (e.g., VCC or reference voltage); sets upper bound of voltage divider range |
| VSS | Ground reference | Return path for all internal logic and resistor array; must be tied to system ground plane |
| INC | Negative-edge-triggered increment input | Falling edge moves wiper one tap; timing-critical (min 4µs cycle time) for reliable position control |
| U/D | Direction control input | HIGH = increment wiper toward VH/RH; LOW = decrement toward VL/RL; sampled synchronously with INC edge |
| CS | Chip select / store enable | LOW = active mode; HIGH with INC HIGH = triggers EEPROM store; HIGH otherwise = standby |
| VL/RL | Low terminal of resistor array | Connects to minimum potential node (e.g., ground or negative rail); defines lower bound of adjustable range |
| VW/RW | Wiper output terminal | Delivers tapped voltage or resistance; series resistance (400–1000Ω @ 2.7V) impacts load regulation in feedback networks |
| VCC | Positive supply | Powers logic and resistor array; must exceed VH, VL, VW at all times per power sequencing requirement |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper storage | Eliminates need for external EEPROM or MCU memory to retain trim settings across power cycles |
| Make-before-break switching | Prevents open-circuit transients during wiper movement - essential for stable bias in op-amp feedback paths |
| 2.7V minimum supply | Enables direct use in modern low-voltage embedded systems (e.g., 3.3V microcontrollers, IoT sensors) |
| 1µA standby current | Supports ultra-low-power applications such as portable medical devices and remote environmental monitors |
| ±300ppm/°C RTOTAL tempco | Ensures predictable resistance drift over industrial temperature range (−40°C to +85°C) |
| Ratiometric operation | Output voltage scales linearly with supply - ideal for ADC reference trimming where VCC serves as reference |

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 | Requires I²C master; higher resolution but no up/down simplicity; tighter tempco | Choose when I²C infrastructure exists and finer granularity is needed over GPIO efficiency |
| MCP41010-I/P | SPI interface; 257-tap resolution; 10kΩ; 2.7–5.5V; 100ppm/°C tempco | Needs SPI peripheral; higher resolution and faster update rate; wider tempco than X9116 | Prefer when high-speed digital trimming or SPI-native host architecture is present |
Compared with AD5171BRMZ-10 and MCP41010-I/P, the X9116WM8IZ-2.7T1 offers lowest GPIO overhead (3-wire up/down), best industrial tempco stability (±300ppm/°C), and guaranteed nonvolatile retention without software intervention - making it optimal for cost-sensitive, low-pin-count embedded trimming where deterministic, minimal-firmware control is required.

FAQ
What is the operating temperature range for the X9116WM8IZ-2.7T1?
The X9116WM8IZ-2.7T1 is rated for −40°C to +85°C industrial temperature operation, confirmed in the Ordering Information table ('I' suffix) and Absolute Maximum Ratings section of FN8160.2. This range applies to both electrical performance and nonvolatile memory endurance specifications, making it suitable for deployment in harsh environments such as factory automation controllers and outdoor telemetry units.
Does the X9116WM8IZ-2.7T1 require an external clock or microcontroller firmware to store wiper position?
No - the X9116WM8IZ-2.7T1 stores wiper position automatically in nonvolatile memory when CS transitions HIGH while INC is held HIGH. This hardware-triggered store requires no clock source or firmware execution; the device enters standby mode immediately after completion. Power-up always recalls the last stored value, ensuring deterministic startup behavior without MCU initialization code.
How does wiper resistance vary with supply voltage in the X9116WM8IZ-2.7T1?
Per the Potentiometer Specifications table in FN8160.2, wiper resistance (RW) for the X9116WM8IZ-2.7T1 is 400Ω to 1000Ω at VCC = 2.7V and 200Ω to 400Ω at VCC = 5V. This voltage-dependent variation arises from CMOS switch on-resistance scaling and must be accounted for in low-impedance feedback networks - especially at 2.7V where RW may dominate total path resistance.
Can the X9116WM8IZ-2.7T1 be used in a two-terminal variable resistor configuration?
Yes - the X9116WM8IZ-2.7T1 supports two-terminal operation by connecting either VH/RH or VL/RL to VW/RW and using the remaining fixed terminal with the wiper. The datasheet's "Basic Configurations" section (page 7) explicitly shows this topology. However, wiper current must remain within ±1mA limits, and total power dissipation must not exceed 10mW to avoid thermal drift or damage.
Is the X9116WM8IZ-2.7T1 RoHS compliant and lead-free?
Yes - the 'Z' suffix in X9116WM8IZ-2.7T1 denotes Pb-free plus anneal construction, meeting RoHS Directive 2011/65/EU requirements. As stated in the Ordering Information footnote, it uses 100% matte tin plate termination and RoHS-compliant molding compounds, qualified for both SnPb and Pb-free soldering processes per IPC/JEDEC J-STD-020.
