Product details
Overview
X9314WSIZ from Intersil is a nonvolatile digitally controlled potentiometer (XDCP™) with 32 log-taper taps, 10kΩ end-to-end resistance, ±5V terminal voltage rating, and three-wire up/down serial interface - used for precision resistance trimming in analog signal conditioning circuits.
For engineers reviewing the X9314WSIZ datasheet, X9314WSIZ pinout, X9314WSIZ application, or X9314WSIZ equivalent, this device supports power-up wiper recall, <500µA standby current, 40Ω typical wiper resistance, and operates from 5V ±10% across -40°C to +85°C in an 8-lead SOIC package.
Technical Context
The X9314WSIZ implements a 5-bit up/down counter driving a 31-element resistor array with make-before-break electronic switches; wiper position is stored in nonvolatile memory on CS↑/INC↑ and recalled at power-up. Its log taper provides 0.07±0.003 step-size linearity per tap.
It uses a three-wire serial interface (CS, U/D, INC) with negative-edge-triggered INC and direction-controlled U/D logic; no clock or data lines are required. Wiper movement halts at physical endpoints without wraparound, and VCC sequencing imposes no restrictions during power-up/down.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-End Resistance | 10kΩ ±20% - defines full-scale analog attenuation range and load matching capability |
| Wiper Resistance | 40Ω typical - limits insertion loss and distortion in low-impedance signal paths |
| Terminal Voltage Range | ±5V - enables bidirectional AC-coupled signal adjustment without external level-shifting |
| Supply Voltage | 5V ±10% - requires stable 4.5–5.5V rail; not compatible with 3.3V-only systems |
| Standby Current | <500µA max - enables low-power retention of trim state during system sleep modes |
| Nonvolatile Retention | 100 years - ensures factory-set or user-calibrated values persist over product lifetime |
| Operating Temperature | -40°C to +85°C - qualified for industrial-grade embedded control and sensor front-ends |
Pinout & Package
Package: 8-lead SOIC (M8.15), RoHS-compliant Pb-free plus anneal finish, body dimensions 4.9mm × 3.9mm × 1.75mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VH/RH | High terminal of resistor array | Fixed endpoint referenced to wiper direction; accepts -5V to +5V; not polarity-fixed |
| VL/RL | Low terminal of resistor array | Fixed endpoint opposite VH/RH; same voltage range; position relative to wiper depends on U/D state |
| VW/RW | Wiper output terminal | Variable tap point; 40Ω series resistance; connects to one of 32 positions via decoded counter |
| VSS | Ground reference | Return path for supply and logic; must be tied to system ground; not floating-capable |
| VCC | Positive supply | 5V ±10% analog/digital supply; powers internal logic, memory, and switch drivers |
| U/D | Direction control input | Active-HIGH selects increment; LOW selects decrement; may be toggled mid-operation |
| INC | Edge-triggered wiper step | Negative-edge triggered; each pulse moves wiper one tap; timing min. 4µs cycle |
| CS | Chip select and store enable | LOW enables device; HIGH with INC=HIGH stores current wiper position to NV memory |
Key Features
| Feature | Design Value |
|---|---|
| Log-taper 32-tap resistor array | Enables precise audio-level attenuation and exponential gain control without external scaling |
| Nonvolatile wiper position storage | Eliminates need for external EEPROM or MCU-based calibration storage on power cycle |
| Three-wire serial interface | Reduces GPIO count vs. SPI/I²C; no clock generation or address decoding required |
| Make-before-break wiper switching | Prevents open-circuit transients during tap transitions; critical for uninterrupted bias networks |
| ±5V terminal voltage tolerance | Supports direct integration into op-amp feedback loops and AC-coupled instrumentation paths |
Applications
| Audio Volume Control | Sensor Offset Calibration |
|---|---|
|
Use Scenario: Adjusting gain in headphone amplifier feedback networks with user-selectable presets. IC Role / Device Role / Timing Role: Two-terminal variable resistor in op-amp inverting configuration, setting closed-loop gain.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5241BRMZ10 | 256-tap I²C interface; 10kΩ; 125ppm/°C tempco; 3.3V/5V supply | Requires I²C host; higher resolution but slower update rate; lacks log taper | Choose when high-resolution linear adjustment and microcontroller I²C availability outweigh need for log response and ultra-low pin count. |
| MCP41010-I/P | 256-tap SPI interface; 10kΩ; 500ppm/°C tempco; 2.7–5.5V supply; volatile memory only | No nonvolatile storage; requires external MCU to reload wiper on startup | Choose when SPI infrastructure exists and calibration persistence is managed externally; avoid where power-loss recovery is mandatory. |
Compared with AD5241BRMZ10 and MCP41010-I/P, the X9314WSIZ delivers deterministic log-taper behavior, zero-software overhead three-wire control, and guaranteed power-up recall - making it optimal for self-contained analog trimming where firmware intervention is undesirable or unavailable.

FAQ
What is the terminal voltage rating of the X9314WSIZ?
The X9314WSIZ supports -5V to +5V on both VH/RH and VL/RL terminals, enabling use in bipolar signal paths such as AC-coupled op-amp stages. This rating is independent of VCC and applies across the full operating temperature range. Exceeding ±5V risks damage to internal transfer gates, and the absolute maximum rating is ±8V - but operation beyond ±5V is not characterized or guaranteed.
Does the X9314WSIZ retain its wiper position after power removal?
Yes, the X9314WSIZ stores the wiper position in nonvolatile memory and automatically recalls it upon power-up. This occurs without any external command or MCU involvement. The stored value persists for up to 100 years under normal conditions, and the recall is completed within 500µs after VCC stabilizes - ensuring immediate operational readiness in safety-critical or unattended systems.
Can the X9314WSIZ be used as a two-terminal variable resistor?
Yes, the X9314WSIZ can operate as a two-terminal variable resistor by connecting either VH/RH or VL/RL to VW/RW and using the remaining fixed terminal with the wiper. In this mode, resistance varies from ~40Ω (wiper at same terminal) to 10kΩ (wiper at opposite terminal). The 40Ω wiper resistance contributes directly to minimum RON, making it suitable for current-sense shunt calibration but not ultra-low-R applications.
What is the wiper resistance specification for the X9314WSIZ?
The X9314WSIZ has a typical wiper resistance of 40Ω, with a maximum of 100Ω across temperature and process variation. This value is measured at ±1mA wiper current and 5V supply. It directly impacts insertion loss and THD in audio paths and introduces a fixed offset in precision current-setting configurations - design margins must account for this series resistance when calculating effective gain or bias accuracy.
Is the X9314WSIZ pin-compatible with other members of the X9314 family?
Yes, all X9314 variants - including X9314WSZ, X9314WMIZ-3, and X9314WSZ-3 - share identical 8-pin SOIC or MSOP footprints and pin functions. The X9314WSIZ uses the SOIC package (M8.15) and is rated for -40°C to +85°C, differing from commercial-grade variants only in temperature range and marking. No PCB layout change is needed when substituting within the same package type.
