Product details
Overview
X9116WS8IZ-2.7 from Intersil is a nonvolatile digitally controlled potentiometer (XDCP™) designed for precision trimming in analog circuits. It features 16 wiper taps, 10kΩ end-to-end resistance, 2.7V to 5.5V supply operation, and a 3-wire up/down serial interface - enabling solid-state replacement of mechanical trimmers in power supply feedback loops, sensor calibration, and DC bias adjustment.
For engineers reviewing the X9116WS8IZ-2.7 datasheet, X9116WS8IZ-2.7 pinout, X9116WS8IZ-2.7 application, or X9116WS8IZ-2.7 equivalent, this page delivers verified technical context, package-specific pin functions, real-world use cases, and validated alternative options - all grounded in the FN8160.2 datasheet and Intersil's official ordering information.
Technical Context
The X9116WS8IZ-2.7 implements a 15-segment linear resistor array with CMOS switch-controlled wiper selection, driven by an up/down counter decoded to one of 16 tap positions. Wiper movement is edge-triggered on INC (falling edge), direction-controlled by U/D logic level, and latched into nonvolatile EEPROM upon CS rising edge while INC is high.
It operates across –40°C to +85°C with RoHS-compliant Pb-free SOIC packaging, supports ratiometric voltage division (VH/VL = VCC/VSS), and maintains wiper position through power cycles via EEPROM storage - with 100,000 write cycles and 100-year data retention confirmed per datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7V to 5.5V - enables direct integration into low-voltage industrial systems without level-shifting. |
| RTOTAL | 10kΩ ±20% - fixed end-to-end resistance suitable for standard gain/offset calibration networks. |
| Wiper Resolution | 16 taps (15 segments) - provides 6.25% step resolution for fine analog tuning. |
| Active Current | <50µA max - minimizes loading in battery-powered or ultra-low-power sensor front-ends. |
| Standby Current | <1µA max - ensures negligible quiescent drain during system sleep modes. |
| Nonvolatile Memory | EEPROM with 100,000 write cycles and 100-year retention - eliminates recalibration after power loss. |
| Temperature Coefficient | ±300 ppm/°C (RTOTAL), ±20 ppm/°C (ratiometric) - supports stable performance across industrial temperature range. |
Pinout & Package
Package: 8-lead SOIC (M8.15), RoHS-compliant Pb-free finish, moisture sensitivity level (MSL) 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VH/RH | High terminal | Fixed end of resistor array; connects to VCC or reference voltage in voltage divider configurations. |
| 2: VCC | Supply voltage | Power input (2.7V–5.5V); must be ≥ VH, VL, and VW per power-up requirements. |
| 3: INC | Increment control input | Falling-edge-triggered; advances or retracts wiper based on U/D state - no internal debouncing required. |
| 4: U/D | Up/down direction control | Logic level sets wiper movement direction during each INC edge; held static during multi-step adjustments. |
| 5: VSS | Ground | Reference node for all analog and digital signals; must be common with system ground plane. |
| 6: CS | Chip select | Active-low enable; rising edge with INC high initiates EEPROM store - critical for persistent setting retention. |
| 7: VL/RL | Low terminal | Fixed end of resistor array; connects to VSS or signal return in variable resistor or divider topologies. |
| 8: VW/RW | Wiper terminal | Movable output node; series resistance 400–1000Ω at 2.7V - impacts loading in high-impedance feedback paths. |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state nonvolatile memory | Eliminates mechanical wear and drift; retains last wiper position across power cycles without external backup. |
| 3-wire up/down serial interface | Requires only three GPIOs (CS, INC, U/D) - simplifies host MCU integration versus SPI/I²C alternatives. |
| 16-tap linear taper | Enables predictable, monotonic voltage division with ±1 MI absolute linearity error - suitable for closed-loop calibration. |
| Low-power operation | Sub-1µA standby current allows use in always-on monitoring circuits without compromising battery life. |
| Pb-free SOIC packaging | MSL1 rating and RoHS compliance support lead-free reflow assembly and long-term industrial supply chain continuity. |
Applications
| Power Supply Feedback Trimming | Sensor Offset Calibration |
|---|---|
|
Use Scenario: Adjusting output voltage of a DC/DC converter by modifying feedback resistor divider ratio. IC Role / Device Role / Timing Role: Digitally programmable resistance element replacing mechanical potentiometer in feedback network.

IC Role / Device Role / Timing Role: Variable resistor in op-amp summing junction or offset injection path. Use Value: Provides stable, temperature-invariant adjustment (±20 ppm/°C ratiometric TC) over –40°C to +85°C. |
| Audio Signal Level Control | Industrial DAC Output Scaling |
|
Use Scenario: Setting gain or attenuation in line-level audio amplifier stages. IC Role / Device Role / Timing Role: Voltage divider between source and amplifier input; wiper drives high-impedance node. Use Value: 16-step resolution and low noise (–120 dBV/√Hz) preserve signal integrity in analog audio paths. |

IC Role / Device Role / Timing Role: Precision resistive divider in reference path of op-amp-based scaling circuit. Use Value: 10kΩ RTOTAL and ±300 ppm/°C TC ensure accurate, stable scaling across operating temperature. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5170BRMZ-10 | I²C interface, 256-tap resolution, 10kΩ, 2.7–5.5V - higher resolution but requires I²C bus and pull-ups. | Better suited for systems needing fine-grained adjustment; incompatible pinout and protocol with X9116WS8IZ-2.7. | Select when I²C infrastructure exists and >16-step granularity is required; not drop-in replaceable. |
| MCP41010-I/P | SPITM interface, 256-tap, 10kΩ, 2.7–5.5V - includes shutdown mode and faster update rate (tCYC = 100ns). | Preferred for high-speed dynamic adjustment; lacks nonvolatile store on power-up - requires host reinitialization. | Choose for SPI-based designs requiring rapid wiper updates; requires firmware changes and external memory for persistence. |
Compared with AD5170BRMZ-10 and MCP41010-I/P, the X9116WS8IZ-2.7 offers simpler GPIO-driven control, guaranteed power-up recall without host intervention, and lower system-level component count - making it optimal for cost-sensitive, low-pin-count industrial trimming where 16-step resolution suffices.

FAQ
What is the supply voltage range supported by the X9116WS8IZ-2.7?
The X9116WS8IZ-2.7 operates from 2.7V to 5.5V, as explicitly specified in the "Supply Voltage (VCC) Limits" section of the FN8160.2 datasheet under the "X9116-2.7" variant. This extended low-voltage capability enables direct use in 3.3V and 5V systems without regulation - unlike standard 5V-only variants such as X9116WS8I.
Does the X9116WS8IZ-2.7 retain its wiper position after power loss?
Yes, the X9116WS8IZ-2.7 stores the last wiper position in nonvolatile EEPROM memory. Upon power-up, it automatically recalls that value - confirmed by the datasheet's "Principles of Operation" and "Endurance And Data Retention" sections, which specify 100-year data retention and 100,000 write cycles.
What package type and lead finish does the X9116WS8IZ-2.7 use?
The X9116WS8IZ-2.7 uses an 8-lead SOIC package (JEDEC MS-012-AA, drawing M8.15) with Pb-free plus anneal finish - verified in the "Ordering Information" table and "NOTE" section of the FN8160.2 datasheet. This meets RoHS compliance and supports both SnPb and Pb-free soldering processes.
How many wiper positions does the X9116WS8IZ-2.7 provide, and what is its resistance tolerance?
The X9116WS8IZ-2.7 provides 16 discrete wiper positions (0–15) across a 15-segment resistor array. Its end-to-end resistance (RTOTAL) is 10kΩ with a tolerance of ±20%, as stated in the "Potentiometer Specifications" table of the FN8160.2 datasheet.
What is the maximum wiper current rating for the X9116WS8IZ-2.7?
The X9116WS8IZ-2.7 supports a maximum wiper current (IW) of ±5.0mA, as defined in the "Potentiometer Specifications" table. Exceeding this may cause irreversible damage - consistent with its role as a trimming device rather than a high-current rheostat.
