Product details
Overview
X9313UMIZ-3 from Intersil is a digitally controlled potentiometer (XDCP™) with 32 linear tap positions, 50 kΩ end-to-end resistance, ±VCC terminal voltage capability, and nonvolatile wiper position storage. It operates from 3V to 5.5V supply and functions as a three-terminal potentiometer or two-terminal variable resistor in analog signal trimming applications.
For engineers reviewing the X9313UMIZ-3 datasheet, X9313UMIZ-3 pinout, X9313UMIZ-3 application, or X9313UMIZ-3 equivalent, key selection criteria include its MSOP-8 package, industrial temperature range (–40°C to +85°C), 3-wire serial interface timing, wiper resistance (40 Ω typ. at VCC = 5V), and nonvolatile store/recall behavior on power-up.
Technical Context
The X9313UMIZ-3 implements a 31-element resistor array with make-before-break wiper switching, enabling glitch-free tap transitions. Its 5-bit up/down counter drives a decoder that selects one of 32 wiper positions, with direction controlled by U/D and edge-triggered increment via INC.
Wiper position is stored in nonvolatile memory when CS rises while INC is HIGH, and automatically recalled at power-on. The device supports terminal voltages from –VCC to +VCC, with absolute linearity error ≤ ±1 MI and ratiometric temperature coefficient of ±20 ppm/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance (RTOTAL) | 50 kΩ ±20% - defines full-scale adjustment range and load interaction in voltage divider configurations |
| Wiper resolution | 32 taps (31 resistive elements) - provides 3.125% step size per tap for fine analog control |
| Supply voltage range | 3V to 5.5V - enables compatibility with both 3.3V and 5V logic systems without level shifting |
| Terminal voltage range | –VCC to +VCC - allows bipolar signal handling and rail-to-rail operation in AC-coupled circuits |
| Wiper resistance | 40 Ω typical at VCC = 5V - limits insertion loss and ensures minimal loading of downstream stages |
| Nonvolatile endurance | 100,000 data changes per bit - supports long-term field calibration and infrequent reprogramming |
| Data retention | 100 years - guarantees wiper setting persistence across product lifetime without backup power |
Pinout & Package
Package: 8-lead MSOP (Pb-free, RoHS compliant), dimensions per JEDEC MO-187-AA (M8.118), body size 3.0 mm × 3.0 mm × 0.85 mm, pitch 0.65 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RH/VH | High terminal | Fixed end of resistor array; referenced as "high" relative to wiper movement direction, not voltage polarity |
| RL/VL | Low terminal | Fixed end of resistor array; referenced as "low" relative to wiper movement direction, not voltage polarity |
| RW/VW | Wiper terminal | Movable contact point; output node whose voltage or resistance varies with digital control; series resistance ~40 Ω |
| VCC | Supply voltage | Positive supply input (3V–5.5V); powers internal logic and resistor array; also sets terminal voltage limits |
| VSS | Ground | Reference node for all digital inputs and analog terminals; must be connected before applying terminal voltages |
| CS | Chip select | Active-low enable; initiates communication and triggers nonvolatile store when rising edge occurs with INC = HIGH |
| U/D | Up/down control | Direction selector for wiper movement; determines whether INC toggles increment or decrement of wiper position |
| INC | Increment input | Negative-edge-triggered clock; advances wiper one tap per valid edge, direction set by U/D state |
Key Features
| Feature | Design Value |
|---|---|
| Solid-state potentiometer architecture | Eliminates mechanical wear, contact bounce, and sensitivity to vibration-ideal for sealed or high-reliability systems |
| 3-wire serial interface | Requires only CS, U/D, and INC signals-no clock or data lines needed; simplifies microcontroller GPIO usage |
| Nonvolatile wiper position storage | Automatically recalls last-set tap at power-on-enables consistent startup behavior without host initialization |
| Temperature-compensated resistor array | ±20 ppm/°C ratiometric TC ensures stable voltage division ratio over industrial temperature range (–40°C to +85°C) |
| Make-before-break wiper switching | Prevents open-circuit transients during tap transitions-critical for maintaining signal continuity in active filters or bias networks |
Applications
| Audio Signal Level Control | DC Bias Voltage Adjustment |
|---|---|
|
Use Scenario: Programmable volume control in professional audio mixers where manual pots are replaced by microcontroller-adjusted gain stages. IC Role / Device Role / Timing Role: Three-terminal potentiometer configured as voltage divider feeding op-amp non-inverting input; wiper position sets attenuation ratio. Use Value: Enables remote or automated calibration, eliminates mechanical drift, and retains user-selected volume after power cycle. |
Use Scenario: Precision biasing of op-amp input offset or transistor base current in sensor front-ends operating across –40°C to +85°C. IC Role / Device Role / Timing Role: Two-terminal variable resistor in emitter degeneration or feedback path; adjusted during factory calibration and held stable thereafter. Use Value: Compensates for component tolerances and thermal drift without requiring EEPROM or external memory management. |
| Power Supply Feedback Trim | Comparator Hysteresis Setting |
|
Use Scenario: Fine-tuning output voltage of adjustable DC-DC converters (e.g., LM317-based regulators) in industrial power modules. IC Role / Device Role / Timing Role: Replaces fixed resistor in feedback divider network; RH/VH connects to output, RL/VL to ground, RW/VW to regulator ADJ pin. Use Value: Allows post-manufacture voltage calibration and field updates without hardware change; 50 kΩ value minimizes current draw from feedback node. |
Use Scenario: Configuring hysteresis window in comparator circuits used for overvoltage/undervoltage detection in battery management systems. IC Role / Device Role / Timing Role: Sets resistor ratio in positive feedback network; wiper position adjusts trip-point separation dynamically based on system state. Use Value: Enables adaptive hysteresis scaling-e.g., wider window during fast transients, narrower during steady-state monitoring. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5243BRMZ50 | I²C interface, dual-channel, 256-tap resolution, 50 kΩ RTOTAL, 2.7V–5.5V supply | Requires I²C master; supports simultaneous dual-pot control; higher resolution but no ±VCC terminal rating | Choose for multi-channel trimming or tighter step resolution; avoid if bipolar terminal voltage or 3-wire simplicity is required. |
| MCP41050-I/P | SPI interface, single-channel, 256-tap resolution, 50 kΩ RTOTAL, 2.7V–5.5V supply, volatile wiper register | Needs external MCU SPI peripheral; no nonvolatile store-requires host reload on power-up | Choose for cost-sensitive designs where host firmware manages calibration persistence; avoid if autonomous power-on restore is mandatory. |
Compared with AD5243BRMZ50 and MCP41050-I/P, the X9313UMIZ-3 uniquely combines 3-wire simplicity, ±VCC terminal tolerance, and guaranteed nonvolatile recall-making it optimal for standalone analog trimming where interface overhead and power-cycle reliability are critical.

FAQ
What is the maximum allowable voltage difference between RH/VH and RL/VL terminals for the X9313UMIZ-3?
The X9313UMIZ-3 supports a maximum voltage difference (ΔV = |VH − VL|) of 10 V, as specified for the X9313U variant in the datasheet. This limit ensures safe operation of the internal resistor array and wiper switches under full-scale analog signal conditions without degradation or latch-up risk.
Does the X9313UMIZ-3 require an external pull-up resistor on the INC, U/D, or CS pins?
No, the X9313UMIZ-3 does not require external pull-up resistors on INC, U/D, or CS. Its digital inputs have CMOS-compatible thresholds (VIL ≤ 0.8 V, VIH ≥ 2 V) and leakage current ≤ ±10 µA, allowing direct connection to microcontroller GPIOs operating at 3.3V or 5V without additional biasing components.
How long does it take for the X9313UMIZ-3 wiper to stabilize after a power-up event?
The X9313UMIZ-3 wiper stabilizes within 10 µs after VCC reaches its final value, as specified by tPU (power-up to wiper stable) in the AC Electrical Specifications table. This rapid settling enables immediate use in time-critical analog paths without waiting for initialization sequences.
Can the X9313UMIZ-3 be used with negative supply voltages applied to RH/VH or RL/VL?
Yes-the X9313UMIZ-3 explicitly supports terminal voltages from –VCC to +VCC. When VCC = 3.3V, RH/VH and RL/VL may swing from –3.3V to +3.3V relative to VSS, enabling true bipolar operation in AC-coupled amplifier stages or differential signal conditioning circuits.
Is the wiper resistance of the X9313UMIZ-3 constant across all tap positions?
Yes-the wiper resistance (RW) of the X9313UMIZ-3 is specified as 40 Ω typical (max 100 Ω) at VCC = 5V and is independent of tap position. This consistency ensures predictable insertion loss and minimal loading variation regardless of selected resistance ratio in voltage divider or variable resistor configurations.
