Product details
Overview
X9250TS24IZ-2.7T1 from Intersil is a quad digitally controlled potentiometer (XDCP™) with 256-tap resolution per channel, SPI serial interface, and dual analog supply rails (V+ = +2.7V to +5.5V, V− = −2.7V to −5.5V). It integrates four independent 100kΩ potentiometers in a single 24-lead SOIC package, supporting precision voltage divider, gain control, and offset adjustment in mixed-signal systems.
For engineers reviewing the X9250TS24IZ-2.7T1 datasheet, X9250TS24IZ-2.7T1 pinout, X9250TS24IZ-2.7T1 application, or X9250TS24IZ-2.7T1 equivalent, key selection criteria include its 2.7V–5.5V VCC range, nonvolatile wiper position storage across four data registers per pot, <5µA standby current, and compatibility with industrial temperature operation (−40°C to +85°C).
Technical Context
The X9250TS24IZ-2.7T1 implements four independent resistor arrays-each with 255 discrete segments and 256 tap points-controlled via an 8-bit Wiper Counter Register (WCR) decoded to select one CMOS switch per array. Each potentiometer features dedicated volatile WCRs and four nonvolatile 8-bit Data Registers (DR0–DR3), enabling persistent wiper state recall on power-up from DR0.
Its SPI interface supports full-duplex communication with CS, SCK, SI, and SO pins, plus device addressing (A0/A1), hardware write protection (WP), and HOLD for serial transaction pausing. The analog section operates from separate V+/V− supplies, allowing true bipolar signal conditioning while digital logic runs from VCC/VSS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total resistance | 100kΩ per potentiometer - sets maximum impedance for voltage division or current limiting in analog feedback paths. |
| Resolution | 256 taps (0.4% step size) - enables fine-grained adjustment of gain, offset, or attenuation with ±1 MI absolute linearity. |
| VCC range | 2.7V to 5.5V - supports direct interfacing with 3.3V or 5V microcontrollers without level-shifting. |
| Analog supply range | V+ = +2.7V to +5.5V, V− = −2.7V to −5.5V - allows rail-to-rail bipolar analog signal handling (e.g., ±2.5V input ranges). |
| Standby current | <5µA total package - minimizes quiescent power in battery-backed or low-power monitoring circuits. |
| Nonvolatile endurance | 100,000 data changes per bit - ensures long-term reliability for field-adjustable calibration storage. |
| Data retention | 100 years - guarantees wiper settings persist over product lifetime without refresh. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5204BRUZ10 | Quad 10kΩ pot, I²C interface, no V+/V− dual analog supply; max VDD = 5.5V only. | Limited to unipolar analog signals; lacks bipolar capability and hardware write protection. | Select when I²C is preferred and bipolar operation is unnecessary; verify layout accommodates different pinout. |
| MCP42050-I/P | Quad 50kΩ pot, SPI interface, single VDD supply (2.7V–5.5V); no separate V+/V− rails. | Cannot support true bipolar signal paths; wiper resistance higher (max 120Ω vs. 150Ω typ). | Choose for cost-sensitive designs requiring only unipolar adjustment; confirm analog signal range fits within VDD–GND. |
Compared with AD5204BRUZ10 and MCP42050-I/P, the X9250TS24IZ-2.7T1 uniquely supports dual-supply analog operation (V+/V−), enabling precision bipolar signal conditioning that neither alternative provides-critical for audio, instrumentation, and industrial sensor interfaces.

FAQ
What is the operating voltage range for the analog section of the X9250TS24IZ-2.7T1?
The X9250TS24IZ-2.7T1 analog section operates from separate V+ and V− supplies: V+ ranges from +2.7V to +5.5V, and V− ranges from −2.7V to −5.5V. This dual-supply architecture enables true bipolar signal handling, such as ±2.5V or ±5V operation, which is essential for precision instrumentation and audio applications where the X9250TS24IZ-2.7T1 delivers stable, low-noise adjustment.
How many nonvolatile data registers does each potentiometer in the X9250TS24IZ-2.7T1 have?
Each of the four potentiometers in the X9250TS24IZ-2.7T1 has four independent 8-bit nonvolatile Data Registers (DR0 through DR3). These registers store wiper positions or system parameters and retain data for 100 years. On power-up, DR0 automatically loads into the corresponding volatile Wiper Counter Register (WCR), ensuring repeatable startup behavior for the X9250TS24IZ-2.7T1.
Does the X9250TS24IZ-2.7T1 support SPI mode 0 (CPOL=0, CPHA=0)?
Yes, the X9250TS24IZ-2.7T1 supports SPI mode 0: data is sampled on the rising edge of SCK (CPHA=0) and the clock idles LOW (CPOL=0). SI data is latched on the rising edge, and SO data is shifted out on the falling edge. This standard timing aligns with most microcontrollers and simplifies firmware integration for the X9250TS24IZ-2.7T1 in SPI-based systems.
What is the maximum wiper current rating for the X9250TS24IZ-2.7T1?
The X9250TS24IZ-2.7T1 specifies a maximum wiper current (IW) of ±7.5mA per potentiometer under +25°C conditions. Exceeding this limit risks degradation of wiper resistance or long-term reliability. For typical use as a voltage divider or gain-setting element, the X9250TS24IZ-2.7T1 remains well within safe operating limits with standard op-amp bias currents and sensor interface loads.
Can the X9250TS24IZ-2.7T1 be used as a two-terminal variable resistor?
Yes, the X9250TS24IZ-2.7T1 can operate as a two-terminal variable resistor by connecting either VH/RH or VL/RL to the same potential (e.g., ground or supply) and using VW/RW with the remaining terminal. This configuration is commonly used for offset nulling or current-source programming, and the X9250TS24IZ-2.7T1 maintains its 0.4% resolution and nonvolatile storage in this mode.
