Product details
Overview
X9313WP-3 from Intersil is a digitally controlled potentiometer (XDCP™) implementing a 32-tap linear resistor array with nonvolatile wiper position storage, 3-wire serial interface (CS/U/D/INC), ±VCC terminal voltage capability, and 10kΩ end-to-end resistance - used for precision analog trimming in voltage regulator feedback loops, sensor calibration circuits, and programmable gain amplifiers.
For engineers reviewing the X9313WP-3 datasheet, X9313WP-3 pinout, X9313WP-3 application, or X9313WP-3 equivalent, key selection criteria include its 3V–5.5V supply range, -40°C to +85°C industrial temperature grade, PDIP-8 package, 10kΩ RTOTAL tolerance (±20%), and nonvolatile recall on power-up without external memory.
Technical Context
The X9313WP-3 integrates a 31-element resistor ladder, 5-bit up/down counter, make-before-break wiper switching network, and EEPROM-based nonvolatile memory. Wiper position is updated on negative-edge transitions of INC while CS is low and direction is set by U/D logic level.
It operates as either a three-terminal potentiometer (RH/VH–RW/VW–RL/VL) or two-terminal variable resistor, with wiper resistance ≤100Ω at VCC = 5V and absolute linearity error limited to ±1 MI (minimum increment = RTOTAL/31).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RTOTAL | 10kΩ ±20% - defines full-scale resistance range for voltage divider or current-limiting use |
| Supply Voltage | 3V to 5.5V - supports mixed-voltage systems including 3.3V and 5V logic domains |
| Operating Temp | -40°C to +85°C - qualified for industrial-grade embedded control and instrumentation |
| Wiper Resolution | 32 taps (31 steps) - provides ~3% step resolution for fine analog adjustment |
| Nonvolatile Store | 100,000 cycles / 100 years retention - enables permanent calibration storage without battery backup |
| Terminal Voltage Range | -VCC to +VCC - allows bipolar signal handling (e.g., ±5V rails) without external level shifters |
| Active Current | ≤3mA max - minimizes system power budget impact during active wiper adjustment |
Pinout & Package
Package: 8-pin PDIP (Plastic Dual-In-Line Package), Pb-free, through-hole compatible per MDP0031 outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Accepts 3V–5.5V; powers internal logic and resistor array |
| VSS | Ground reference | Return path for supply and signal currents; must be low-impedance |
| RH/VH | High terminal | Fixed end of resistor array; voltage may range from -VCC to +VCC |
| RL/VL | Low terminal | Fixed opposite end; polarity relative to wiper direction, not absolute voltage |
| RW/VW | Wiper output | Movable tap point; series resistance ≤100Ω at 5V; connects to load or feedback node |
| CS | Chip select | Active-low enable; HIGH initiates nonvolatile store when INC is also HIGH |
| U/D | Direction control | Logic level sets wiper increment/decrement on next INC edge |
| INC | Increment clock | Negative-edge triggered; advances wiper one tap per valid transition |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state construction | Eliminates mechanical wear, contact bounce, and environmental sensitivity of trim pots |
| 3-wire serial interface | Requires only CS, U/D, and INC signals - no SPI/I²C controller needed |
| Nonvolatile wiper recall | Restores last stored position at power-on - ensures repeatable startup behavior |
| Temperature-compensated array | ±300 ppm/°C RTOTAL drift - maintains ratio accuracy across industrial temperature range |
| Make-before-break switching | Prevents open-circuit transients during wiper movement - critical for stable feedback paths |
Applications
| Power Supply Feedback Trimming | Sensor Offset Calibration |
|---|---|
Use Scenario: Adjusting output voltage of adjustable DC-DC converters (e.g., LM317, LT308x) via resistor divider feedback network. IC Role / Device Role / Timing Role: Replaces mechanical potentiometer in voltage-setting divider; wiper position sets VOUT = 1.25V × (1 + RH/RW). Use Value: Enables factory-programmed or field-updatable output voltage without hardware change; retains setting across power cycles. | Use Scenario: Nulling thermal or process-induced offset in bridge-based pressure or temperature sensors. IC Role / Device Role / Timing Role: Two-terminal variable resistor in op-amp summing junction or Wheatstone bridge leg. Use Value: Achieves <±1 mV offset correction over -40°C to +85°C using nonvolatile storage - eliminates manual calibration labor. |
| Programmable Gain Amplifier | Comparator Hysteresis Setting |
Use Scenario: Configuring closed-loop gain of instrumentation amplifiers (e.g., INA128) via feedback resistor ratio. IC Role / Device Role / Timing Role: Three-terminal potentiometer where RH and RL set gain-determining resistive ratio and RW adjusts dynamically. Use Value: Supports software-selectable gain steps (e.g., ×1, ×10, ×100) with <3% step resolution and no external DAC or MCU GPIO overhead. | Use Scenario: Setting hysteresis window in comparator circuits (e.g., TL072, LT311A) for noise-immune threshold detection. IC Role / Device Role / Timing Role: Variable resistor in positive feedback path; RH–RW–RL forms adjustable voltage divider feeding back to non-inverting input. Use Value: Allows digital tuning of hysteresis width (e.g., 10mV–500mV) with nonvolatile recall - prevents false triggering in noisy industrial 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 |
|---|---|---|---|
| AD5243BRMZ10 | I²C interface, dual-channel, 256-tap resolution, 10kΩ, ±30% RTOTAL tolerance | Requires I²C master; higher resolution but looser resistance tolerance affects absolute accuracy | Choose for multi-channel or higher-resolution trimming where I²C infrastructure exists |
| MCP41010-I/P | SPITM interface, single-channel, 256-tap, 10kΩ, ±20% RTOTAL, volatile wiper register only | No nonvolatile storage - requires external MCU to reload wiper on power-up | Choose for cost-sensitive designs where calibration is reloaded at boot and layout space is constrained |
Compared with AD5243BRMZ10 and MCP41010-I/P, the X9313WP-3 offers deterministic 3-wire control without protocol overhead, guaranteed nonvolatile recall, and tighter voltage-range compatibility (±VCC terminals), making it optimal for standalone analog trimming where reliability and simplicity outweigh resolution needs.

FAQ
What is the maximum allowable voltage across RH and RL terminals for X9313WP-3?
The X9313WP-3 supports ΔV = |VH − VL| up to 10V under recommended operating conditions. This is specified for X9313W-series devices in the Absolute Maximum Ratings table and confirmed in the Recommended Operating Conditions section of the FN8177 datasheet. Exceeding this differential voltage risks irreversible damage to the internal resistor array or switching elements.
Does X9313WP-3 require an external pull-up or pull-down resistor on the INC, U/D, or CS pins?
No, the X9313WP-3 does not require external biasing resistors on INC, U/D, or CS. Its input leakage current is ±10µA maximum, and VIH/VIL thresholds are defined relative to VCC and VSS (VIH ≥ 2V, VIL ≤ 0.8V for VCC = 5V). Direct connection to CMOS logic outputs meets all interface requirements without additional components.
Can X9313WP-3 operate with a 3.3V supply while driving ±3.3V signals on RH/VL terminals?
Yes. The X9313WP-3 supports terminal voltages from -VCC to +VCC. With VCC = 3.3V, RH and RL may swing from -3.3V to +3.3V, enabling true bipolar operation in 3.3V systems - such as audio signal path trimming or dual-supply op-amp configurations - without level-shifting circuitry.
How many wiper position changes can X9313WP-3 endure before failure?
The X9313WP-3 guarantees a minimum endurance of 100,000 data changes per bit in its nonvolatile memory, as stated in the Endurance and Data Retention table. This applies to wiper position stores (not incremental moves), and each store cycle writes the full 5-bit wiper value. Field usage exceeding this count may result in loss of nonvolatile recall capability.
Is the X9313WP-3 RoHS compliant and lead-free?
Yes. The X9313WP-3 is Pb-free and RoHS compliant, as explicitly noted in the Ordering Information table (Page 2) and the "NOTE" section describing Intersil's Pb-free packaging. It uses 100% matte tin (e3) termination finish and conforms to IPC/JEDEC J-STD-020 reflow profiles for lead-free assembly.
