Product details
Overview
X9015WS8Z-2.7 from Intersil is a volatile, digitally controlled potentiometer with 32-tap resolution, 10kΩ end-to-end resistance, and 2.7V–5.5V supply operation. It implements a three-wire up/down serial interface (CS/INC/U/D), features 50µA max active current and 1µA max standby current, and powers up at Tap #15 - used for precision analog trimming in low-power sensor signal conditioning circuits.
For engineers reviewing the X9015WS8Z-2.7 datasheet, X9015WS8Z-2.7 pinout, X9015WS8Z-2.7 application, or X9015WS8Z-2.7 equivalent, this page delivers verified electrical specs, SOIC-8 package mapping, wiper resistance behavior at 2.7V, absolute linearity (±1 MI), and real-world use cases in voltage reference adjustment and DC bias control.
Technical Context
The X9015WS8Z-2.7 integrates a 5-bit up/down counter, decoder, and 31-resistor string to position a make-before-break electronic wiper across 32 discrete taps. Its control logic responds to negative-edge-triggered INC pulses while U/D determines direction, and CS enables selection or entry into 1µA standby mode.
Operation is strictly volatile: wiper position resets to Tap #15 on power-up, with no nonvolatile storage. Wiper resistance varies from 400Ω to 1000Ω at VCC = 2.7V, and total resistance exhibits ±300 ppm/°C temperature coefficient - critical for stable gain/bias setting in ambient-varying environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-End Resistance | 10kΩ ±20% - sets full-scale analog range for voltage divider or variable gain applications |
| Supply Voltage Range | 2.7V–5.5V - enables direct compatibility with 3.3V and 5V systems without level-shifting |
| Active Supply Current | 50µA max - supports battery-powered or ultra-low-power sensor front-ends |
| Standby Current | 1µA max - allows host MCU to idle X9015WS8Z-2.7 between trim updates |
| Wiper Resistance | 400–1000Ω at 2.7V - impacts loading error in high-impedance feedback paths |
| Absolute Linearity | ±1 MI (Minimum Increment) - ensures ≤3.2% full-scale error in tap-to-tap voltage step accuracy |
| Power-Up State | Tap #15 (midpoint) - guarantees known default bias point after cold start |
Pinout & Package
Package: 8-lead narrow-body SOIC (JEDEC MS-012-AA, outline M8.15), RoHS-compliant, matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RH/VH | High-side fixed terminal | Connects to VCC or maximum analog rail; defines upper voltage limit of potentiometer |
| 2 - CS | Chip select input | Active-low enable; drives device into 1µA standby when HIGH during INC idle |
| 3 - INC | Increment control input | Negative-edge-triggered; advances wiper position per pulse, direction set by U/D |
| 4 - U/D | Up/down direction control | HIGH = increment toward RH/VH; LOW = decrement toward RL/VL |
| 5 - RL/VL | Low-side fixed terminal | Connects to VSS or minimum analog rail; defines lower voltage limit |
| 6 - VSS | Ground reference | Return path for supply and analog signals; must be low-impedance for noise performance |
| 7 - VCC | Positive supply | 2.7V–5.5V operation; powers internal logic and resistor array |
| 8 - RW/VW | Wiper output terminal | Provides tapped voltage/current; series resistance 400–1000Ω at 2.7V affects load regulation |
Key Features
| Feature | Design Value |
|---|---|
| 32-tap volatile digital potentiometer | Enables precise, repeatable analog trimming without EEPROM wear-out or write latency |
| Three-wire up/down serial interface | Requires only three GPIOs (CS/INC/U/D); eliminates need for SPI/I²C peripherals or address decoding |
| 2.7V–5.5V wide supply range | Supports direct integration into mixed-voltage systems including 3.3V microcontrollers and 5V analog stages |
| Make-before-break wiper switching | Prevents open-circuit transients during tap transitions - critical for stable op-amp feedback networks |
| 1µA standby current | Permits continuous connection to VCC while minimizing quiescent power in always-on monitoring circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| X9015US8Z-2.7 | Same electrical specs and SOIC-8 package; marked "X9015U ZF" vs "X9015W ZF"; recommended replacement per datasheet | No functional difference; identical pinout, timing, and performance - drop-in substitute for new designs | Select X9015US8Z-2.7 for new designs where long-term availability and documented support are prioritized. |
| MCP41010-I/P | 10kΩ, SPI interface, 2.7–5.5V, but nonvolatile (EEPROM); higher ICC (125µA active) | Retains wiper position through power cycles - suitable where persistent settings are required | Choose MCP41010-I/P only if nonvolatility is mandatory; otherwise X9015WS8Z-2.7 offers lower power and simpler control. |
Compared with X9015US8Z-2.7, the X9015WS8Z-2.7 shares identical functionality but is marked as obsolete with recommended replacement; versus MCP41010-I/P, it trades nonvolatility for 2.5× lower active current and GPIO-friendly up/down interface - favoring low-power, transient-trim applications.

FAQ
What is the power-up wiper position for the X9015WS8Z-2.7?
The X9015WS8Z-2.7 powers up with its wiper at Tap #15 - the midpoint of its 32-tap resistor string. This deterministic reset behavior ensures a known, repeatable starting point for analog bias or gain settings after each power cycle, eliminating uncertainty in system initialization sequences.
Does the X9015WS8Z-2.7 retain wiper position after power loss?
No, the X9015WS8Z-2.7 is a volatile digital potentiometer and does not retain wiper position after power removal. Upon reapplication of VCC, the wiper automatically returns to Tap #15. This behavior is inherent to its architecture and confirmed in the FN8157 datasheet Section "Principles Of Operation".
What is the wiper resistance of the X9015WS8Z-2.7 at 2.7V supply?
At VCC = 2.7V, the X9015WS8Z-2.7 exhibits a wiper resistance (RW) of 400Ω to 1000Ω, as specified in the "Potentiometer Specifications" table on page 4 of FN8157 Rev 6.00. This range directly impacts loading error in high-impedance feedback configurations and must be accounted for in precision divider designs.
Can the X9015WS8Z-2.7 operate from a 3.3V supply?
Yes, the X9015WS8Z-2.7 supports VCC from 2.7V to 5.5V, making 3.3V fully compliant. Its logic thresholds (VIH ≥ 0.7×VCC, VIL ≤ 0.1×VCC) and 50µA max ICC ensure reliable operation with standard 3.3V microcontroller GPIOs driving CS, INC, and U/D pins.
Is the X9015WS8Z-2.7 pin-compatible with other X9015 variants in SOIC-8?
Yes, all X9015 variants in 8-lead SOIC (including X9015WS8Z-2.7, X9015US8Z-2.7, and X9015US8Z) share identical pinout, package dimensions (M8.15), and electrical interface - confirmed by the common Pin Descriptions section and Package Outline Drawing on pages 2–3 and 11 of FN8157 Rev 6.00.
