Product details
Overview
X9116WM8IZ-2.7 from Intersil is a solid-state, nonvolatile digitally controlled potentiometer (XDCP™) designed for precision trimming in industrial-grade analog circuits. It provides 16 wiper positions across a 10kΩ linear resistor array, operates from 2.7V to 5.5V, consumes ≤1µA in standby, and retains wiper position in EEPROM after power cycling. It replaces mechanical trimmers in voltage divider and gain-setting applications requiring long-term stability.
For engineers reviewing the X9116WM8IZ-2.7 datasheet, X9116WM8IZ-2.7 pinout, X9116WM8IZ-2.7 application, or X9116WM8IZ-2.7 equivalent, this page delivers verified electrical specs, true pin functions, industrial temperature range (-40°C to +85°C), Pb-free MSOP-8 packaging, and real-world trimmer replacement use cases - all confirmed against Intersil FN8160.2 (2006).
Technical Context
The X9116WM8IZ-2.7 implements a 4-bit up/down counter driving a 15-segment resistor ladder via CMOS switches with make-before-break switching. Its 3-wire serial interface (CS, INC, U/D) enables discrete tap control without clock or data lines, and wiper position is stored in nonvolatile memory only when CS rises while INC is HIGH.
It supports ratiometric operation with VH/VL terminals referenced to VCC/VSS, exhibits ±300 ppm/°C end-to-end resistance drift, and maintains <±1 MI absolute linearity over temperature. Wiper resistance varies from 400Ω to 1000Ω at 2.7V, directly impacting low-voltage signal path impedance matching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7V to 5.5V - Enables direct integration into 3.3V and 5V systems without level-shifting. |
| RTOTAL | 10kΩ ±20% - Fixed end-to-end resistance suitable for standard gain/offset calibration networks. |
| Wiper Positions | 16 taps (0–15) - Provides 6.25% resolution per step for fine analog adjustment. |
| Standby Current | <1µA - Allows battery-powered or always-on systems to retain trim state with negligible quiescent drain. |
| Nonvolatile Storage | 100,000 write cycles / 100-year retention - Guarantees lifetime calibration integrity without external EEPROM. |
| Temperature Range | -40°C to +85°C - Qualified for industrial environments including motor drives and sensor signal conditioning. |
| Package | 8-lead MSOP (M8.118), Pb-free - Compact surface-mount footprint compatible with automated assembly and RoHS compliance. |
Pinout & Package
Package: 8-lead Mini Small Outline Plastic Package (MSOP), JEDEC MO-187AA compliant, body dimensions 3.0mm × 3.0mm × 0.85mm (D × E × A), moisture sensitivity level (MSL) 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VH/RH | High terminal of resistor array | Connects to VCC or maximum analog rail; defines upper voltage boundary of divider. |
| 2: VCC | Positive supply input | Must be ≥ VH, VL, VW; powers internal logic and switch drivers; supports 2.7–5.5V operation. |
| 3: INC | Active-low increment control | Falling edge triggers wiper movement; timing-critical (tCYC = 4µs min); requires tIW ≤5µs wiper settling. |
| 4: U/D | Direction control input | HIGH = wiper increments toward VH; LOW = decrements toward VL; sampled on each INC edge. |
| 5: VSS | Ground reference | Return path for supply and signal; must be common with system ground for accurate ratiometric operation. |
| 6: CS | Chip select / store enable | LOW enables serial interface; HIGH while INC=HIGH initiates nonvolatile store (tCPH = 10ms). |
| 7: VL/RL | Low terminal of resistor array | Connects to VSS or minimum analog rail; defines lower voltage boundary of divider. |
| 8: VW/RW | Wiper output terminal | Delivers tapped voltage; series resistance 400–1000Ω at 2.7V affects loading in high-impedance feedback paths. |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state nonvolatile memory | Eliminates mechanical wear and drift; stores last wiper position across power cycles without backup power. |
| Make-before-break wiper switching | Prevents open-circuit transients during tap transitions, critical for stable biasing in amplifier feedback loops. |
| 2.7V minimum supply operation | Enables direct use in 3.3V microcontroller systems without regulator overhead or voltage translation. |
| ±20 ppm/°C ratiometric tempco | Ensures stable voltage division ratio over temperature, essential for precision sensor scaling and ADC reference trimming. |
| 10kΩ end-to-end resistance | Optimized for low current draw in voltage dividers while maintaining sufficient SNR in noise-sensitive analog stages. |
Applications
| Power Supply Output Trim | ADC Reference Voltage Calibration |
|---|---|

IC Role / Device Role / Timing Role: Two-terminal variable resistor in current-setting leg or offset compensation network. Use Value: Compensates for sensor unit-to-unit variation and PCB trace resistance; industrial temp range ensures stability in harsh environments. |
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, but higher standby current (5µA) and no MSOP-8 Pb-free option in industrial grade. | Requires I²C master; better resolution but less suited for simple GPIO-based trimming in resource-constrained MCUs. | Choose AD5171BRMZ-10 if I²C infrastructure exists and finer resolution is required; avoid if minimal GPIO count or ultra-low ISB is critical. |
| MCP41010-I/P | 3-wire SPI interface, 10kΩ, 2.7–5.5V, PDIP-8 package only, commercial temp range (0°C to +70°C), no nonvolatile store on power-up. | Lacks industrial temperature rating and automatic power-up recall; requires host MCU to reinitialize wiper position. | Choose MCP41010-I/P for prototyping or commercial-grade cost-sensitive designs; not suitable for unattended industrial equipment. |
Compared with X9116WM8IZ-2.7, AD5171BRMZ-10 offers higher resolution but sacrifices ultra-low standby current and industrial reliability, while MCP41010-I/P lacks temperature rating and nonvolatile recall - making X9116WM8IZ-2.7 the only choice for maintenance-free, field-calibrated industrial trim applications.

FAQ
What is the guaranteed operating temperature range for X9116WM8IZ-2.7?
The X9116WM8IZ-2.7 is rated for -40°C to +85°C operation, as confirmed in the Intersil ordering information table (FN8160.2, p.2). This industrial temperature grade is validated across all electrical specifications including RTOTAL tolerance, wiper resistance, and nonvolatile memory endurance - ensuring reliable performance in motor drives, PLC modules, and outdoor sensor nodes where ambient extremes occur.
Does X9116WM8IZ-2.7 require an external clock or microcontroller firmware to retain its wiper position after power loss?
No. The X9116WM8IZ-2.7 stores the last wiper position in on-chip nonvolatile EEPROM automatically upon valid store command (CS rising edge with INC HIGH), and recalls it at next power-up without any external intervention. This self-contained behavior is intrinsic to the X9116WM8IZ-2.7 architecture and requires no clock, firmware, or backup power source.
Can X9116WM8IZ-2.7 be used as a two-terminal variable resistor, and what is its maximum allowable wiper current?
Yes, X9116WM8IZ-2.7 supports two-terminal operation (e.g., VL–VW or VH–VW) with ±1mA maximum wiper current, as specified in the Potentiometer Specifications table (FN8160.2, p.4). Exceeding this limit risks irreversible damage to the internal CMOS switches; design must ensure current stays within ±1mA under all operating voltages and tap positions.
What is the wiper resistance of X9116WM8IZ-2.7 at 2.7V supply, and how does it affect circuit accuracy?
At 2.7V supply, the wiper resistance of X9116WM8IZ-2.7 is 400Ω to 1000Ω (FN8160.2, p.4). This series impedance introduces gain error in high-impedance feedback paths - for example, in a 10kΩ divider, it adds up to 10% relative error at worst-case 1000Ω. Designers must account for this in precision applications by using buffer amplifiers or selecting lower RTOTAL values where feasible.
Is X9116WM8IZ-2.7 RoHS compliant, and what does the 'Z' suffix indicate in its part number?
Yes, X9116WM8IZ-2.7 is RoHS compliant. The 'Z' suffix explicitly denotes Pb-free plus anneal construction per Intersil's specification (FN8160.2, p.2), featuring 100% matte tin plate termination and compatible molding compounds - certified to meet IPC/JEDEC J-STD-020 reflow requirements for both SnPb and lead-free soldering processes.
