Product details
Overview
X9511WS from Intersil is a push-button controlled digital potentiometer (XDCP™) with 32 linear tap positions, 10kΩ end-to-end resistance, ±5V terminal voltage range, and nonvolatile wiper position storage. It replaces mechanical potentiometers in analog trimming applications requiring manual adjustment without microcontroller interface.
For engineers reviewing the X9511WS datasheet, X9511WS pinout, X9511WS application, or X9511WS equivalent, this device supports manual resistance tuning via two push buttons, offers AUTOSTORE® and manual store modes, retains wiper position for 100 years, operates at 5V ±10%, and delivers ±1.0 MI absolute linearity in voltage divider mode.
Technical Context
The X9511WS implements a 5-bit up/down counter driving a 32-position decoder to select taps across a 31-element resistor array. Its internal debounce circuitry enforces ≥40ms minimum pulse width on PU/PD inputs, enabling both single-step and fast-scan adjustment modes.
Wiper position is stored in EEPROM memory either automatically during VCC power-down (when ASE = LOW) or manually via ASE pulse (ASE = HIGH → LOW → HIGH). The device maintains ratiometric temperature coefficient of ±20 ppm and typical wiper resistance of 40Ω, supporting stable analog signal conditioning across 0°C to +70°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total resistance | 10kΩ ±20% - defines full-scale analog gain/attenuation range in voltage divider or rheostat configurations. |
| Terminal voltage range | −5V to +5V - enables bipolar signal conditioning without external level-shifting circuitry. |
| Supply voltage | 5V ±10% - compatible with standard logic rails; no separate analog supply required. |
| Active current | ≤3mA - allows direct connection to battery-powered systems without significant load impact. |
| Standby current | 100µA typical - supports low-power sleep states between adjustments. |
| Resolution | 3% - corresponds to 323Ω per tap (10kΩ/31), sufficient for coarse analog calibration. |
| Linearity | ±1.0 MI absolute, ±0.2 MI relative - ensures monotonic output and predictable step error in feedback loops. |
| Data retention | 100 years - eliminates need for periodic recalibration or backup power in field-deployed equipment. |
Pinout & Package
Package: 8-lead SOIC (MDP0027), RoHS-compliant Pb-free finish, body dimensions 4.9mm × 6.0mm × 1.75mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VH | High terminal | Fixed end of resistor array; referenced to VL for voltage divider operation; accepts −5V to +5V. |
| VW | Wiper terminal | Output node connected to selected tap; wiper resistance ≤100Ω ensures minimal loading in sensor biasing. |
| VL | Low terminal | Fixed end opposite VH; completes resistive path; same voltage rating as VH. |
| VSS | Ground | Logic and analog reference ground; must be tied to system common; not isolated from VH/VL return paths. |
| VCC | Supply voltage | 5V ±10% digital/analog supply; powers counter, EEPROM, and decode logic; no separate AVCC required. |
| PU | Push-up input | Debounced active-low control; increments wiper position; internal pull-up eliminates external resistor. |
| PD | Push-down input | Debounced active-low control; decrements wiper position; independent timing from PU; supports simultaneous button use. |
| ASE | AUTOSTORE enable | Selects auto-store (LOW) or manual-store (HIGH); rising edge triggers EEPROM write; no external clock needed. |
Key Features
| Feature | Design Value |
|---|---|
| Push-button interface | Eliminates need for I²C/SPI host controller; reduces BOM count and firmware complexity in simple trim applications. |
| AUTOSTORE® function | Automatically saves last wiper position on VCC ramp-down, ensuring consistent startup behavior without user intervention. |
| Manual store option | Enables intentional calibration capture via ASE push button, supporting field recalibration without power cycle. |
| Temperature-compensated array | ±300 ppm/°C typical TCR and ±20 ppm ratiometric coefficient maintain resistance ratio stability over 0°C to +70°C. |
| Slow/fast scan modes | First-second slow mode (100–375ms/tap) prevents overshoot; >1s hold triggers fast mode (25–90ms/tap) for rapid coarse adjustment. |
| Nonvolatile wiper storage | 100,000 store cycles endurance supports lifetime recalibration in test fixtures and production line setups. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5171BRMZ-10 | I²C interface, 64-tap, 10kΩ, 2.7–5.5V supply, no push-button control. | Requires microcontroller host; unsuitable for standalone manual trim; higher resolution but no AUTOSTORE. | Choose when system already includes I²C bus and firmware support for dynamic adjustment. |
| MCP4017T-103 | Up/down interface (not push-button debounced), 64-tap, 10kΩ, 1.8–5.5V, volatile wiper position. | No nonvolatile storage; wiper resets to mid-scale on power-up; lacks slow/fast scan and AUTOSTORE. | Choose for cost-sensitive, low-voltage designs where power-cycle reset is acceptable. |
Compared with AD5171BRMZ-10 and MCP4017T-103, the X9511WS uniquely combines push-button simplicity, nonvolatile storage, and bipolar voltage capability-making it optimal for unattended, field-serviceable analog trimming where MCU resources or board space are constrained.

FAQ
What is the operating temperature range for the X9511WS?
The X9511WS is specified for commercial-grade operation from 0°C to +70°C. This range is confirmed in the Ordering Information table of the FN8205 datasheet, where "X9511WS" is explicitly listed with "0 to +70°C" under Temperature Range. It uses the same die and characterization as the X9511W series, and its SOIC package (MDP0027) is rated for this thermal envelope.
Does the X9511WS require an external microcontroller to operate?
No, the X9511WS does not require an external microcontroller. It is designed for standalone push-button operation: PU and PD inputs accept momentary switch closures to increment or decrement the wiper, while ASE controls AUTOSTORE® or manual store. All logic, debounce, EEPROM storage, and decoding are fully integrated within the X9511WS die.
What is the maximum voltage that can be applied across VH and VL terminals of the X9511WS?
The maximum differential voltage |VH − VL| for the X9511WS is 10V, as stated in the Absolute Maximum Ratings table under "ΔV = |VH − VL| X9511W". Since X9511WS shares the same 10kΩ resistance and core architecture, this 10V limit applies directly. Individual terminal voltages must remain within −5V to +5V referenced to VSS.
How many times can the wiper position be stored in the X9511WS EEPROM?
The X9511WS supports up to 100,000 wiper position store operations, as documented in the "Wiper position store operations" line under Physical Characteristics in the FN8205 datasheet. This endurance rating applies to both AUTOSTORE cycles (triggered by VCC ramp-down) and manual store cycles (triggered by ASE pulse), and is guaranteed across the full 0°C to +70°C operating range.
Is the X9511WS RoHS compliant?
Yes, the X9511WS is RoHS compliant. The datasheet explicitly states "Pb-free plus anneal available (RoHS compliant)" and lists "X9511WSZ*, **(Note)" as the Pb-free version with "8 Ld SOIC (Pb-free)" packaging. The note confirms use of 100% matte tin plate termination finish and RoHS-compliant molding compounds, meeting IPC/JEDEC J-STD-020 reflow requirements.
