Product details
Overview
X9250UV24-2.7 from Intersil is a quad digitally controlled potentiometer (XDCP™) with 256-tap resolution per channel, SPI serial interface, dual analog supply support (V+ = +2.7V to +5.5V, V– = –2.7V to –5.5V), and 50kΩ end-to-end resistance. It operates across 0°C to +70°C in a 24-lead TSSOP package and is used for precision analog signal conditioning in programmable gain amplifiers and voltage regulator feedback networks.
For engineers reviewing the X9250UV24-2.7 datasheet, X9250UV24-2.7 pinout, X9250UV24-2.7 application, or X9250UV24-2.7 equivalent, key selection criteria include its nonvolatile wiper position storage, <5µA standby current, 0.4% resolution, hardware write protection (WP), and compatibility with 2.7V–5.5V digital supply (VCC) and bipolar analog supplies.
Technical Context
The X9250UV24-2.7 integrates four independent 255-segment resistor arrays, each controlled by an 8-bit volatile Wiper Counter Register (WCR) and backed by four 8-bit nonvolatile Data Registers (DR0–DR3). Wiper position is updated via SPI commands including direct WCR load, DR-to-WCR transfer, and increment/decrement mode.
It supports full SPI protocol compliance with CS, SCK, SI, and SO signals, plus HOLD for serial pause and A0/A1 for device addressing (up to 4 devices on bus). Analog section isolation is maintained by separate V+, V–, and VCC supplies, enabling true bipolar operation with ±2.7V to ±5.5V analog rail capability and 100-year data retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 256 taps per potentiometer → 0.4% step resolution for precise analog adjustment |
| End-to-end resistance | 50kΩ ±20% → sets gain/attenuation range in amplifier and regulator circuits |
| Supply ranges | VCC = 2.7V–5.5V; V+ = +2.7V–+5.5V; V– = –2.7V––5.5V → enables single-supply digital control of bipolar analog paths |
| Standby current | <5µA total package → suitable for low-power battery-backed systems |
| Nonvolatile endurance | 100,000 data changes per bit per register → supports frequent calibration updates over product lifetime |
| Wiper resistance | 150Ω–250Ω typical at ±1mA → limits loading error in high-impedance feedback nodes |
| SPI clock frequency | Up to 2MHz → allows fast reconfiguration during system initialization or dynamic tuning |
Pinout & Package

| A0, A1 | Device Address | Set LSBs of 8-bit slave address; allow up to four X9250UV24-2.7 devices on one SPI bus |
| HOLD | Serial Pause Control | Pauses ongoing SPI transaction without resetting state; requires SCK LOW before assertion |
| WP | Hardware Write Protect | LOW disables nonvolatile writes to Data Registers - prevents accidental calibration loss |
| VH0–VH3 / VL0–VL3 | Potentiometer Terminals | Fixed high/low ends of each 50kΩ resistor array; connect to analog rails or signal path endpoints |
| VW0–VW3 | Wiper Outputs | Digitally positioned tap points; deliver adjustable voltage/current to amplifier inputs or feedback nodes |
| V+, V– | Analog Supplies | Independent bipolar analog power rails; define usable voltage swing for all four pots |
| VCC, VSS | Digital Supply/Ground | 2.7V–5.5V logic supply; isolated from analog section to minimize noise coupling |
Key Features

Use Scenario: Dynamically setting output voltage of adjustable LDOs or switching regulators via feedback divider. IC Role / Device Role / Timing Role: Replaces fixed R1/R2 divider; VWx node connects to regulator ADJ pin while VHx/VLx set divider ratio. Use Value: Supports remote voltage trimming, factory calibration, and adaptive output scaling - all with 0.4% step accuracy and no external EEPROM. |
| Comparator Hysteresis Control | Audio Channel Balance |
Use Scenario: Setting upper/lower threshold voltages in window comparators for sensor over-range detection. IC Role / Device Role / Timing Role: Configures hysteresis resistor network between comparator output and input; two pots set VUL and VLL. Use Value: Allows real-time hysteresis adjustment to match varying noise profiles; 100k-year data retention preserves calibrated thresholds. |
Use Scenario: Balancing left/right channel levels in professional audio mixers or headphone amplifiers. IC Role / Device Role / Timing Role: Functions as dual-channel attenuator in line-level signal path; VW0/VW1 drive differential inputs of audio DAC or amp. Use Value: Eliminates mechanical pot drift and channel mismatch; 50kΩ matching tolerance and <150Ω wiper resistance preserve signal integrity. |
Equivalent & Alternatives

FAQ
What is the operating temperature range for the X9250UV24-2.7?
The X9250UV24-2.7 is rated for 0°C to +70°C operation, as confirmed in the Ordering Information table (Page 2) and Recommended Operating Conditions (Page 11) of FN8165 Rev.3.00. This commercial-grade rating distinguishes it from industrial variants like X9250UV24I-2.7 (–40°C to +85°C) and confirms its suitability for indoor, non-extreme environmental applications.
Does the X9250UV24-2.7 support true bipolar analog operation?
Yes, the X9250UV24-2.7 supports true bipolar analog operation via dedicated V+ and V– supply pins, rated from –2.7V to –5.5V and +2.7V to +5.5V respectively. This enables full rail-to-rail wiper voltage swing across both positive and negative domains - a capability verified in the Absolute Maximum Ratings (Page 11) and Potentiometer Characteristics tables.
How many nonvolatile data registers does the X9250UV24-2.7 provide per potentiometer?
The X9250UV24-2.7 provides four 8-bit nonvolatile Data Registers (DR0–DR3) for each of its four potentiometers, as specified in the FEATURES section (Page 1) and DEVICE DESCRIPTION (Page 4). These registers store wiper positions or system parameters with 100-year data retention and 100,000-cycle endurance.
What is the maximum SPI clock frequency supported by the X9250UV24-2.7?
The X9250UV24-2.7 supports a maximum SPI clock frequency of 2.0 MHz, as defined in the AC Timing specifications (Page 13, fSCK parameter). This timing is validated across the full operating voltage and temperature range and enables sub-10ms full-register configuration sequences.
Can the X9250UV24-2.7 be used as a two-terminal variable resistor?
Yes, the X9250UV24-2.7 can be configured as a two-terminal variable resistor by connecting either VHx or VLx to the wiper (VWx) terminal and using the remaining terminal as the adjustable endpoint - a configuration explicitly supported in the DESCRIPTION section (Page 1) and Application Circuits (Page 17).
