Product details
Overview
X9250TS24-2.7T1 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 three-terminal potentiometer or two-terminal variable resistor configurations for precision analog control in mixed-signal systems.
For engineers reviewing the X9250TS24-2.7T1 datasheet, X9250TS24-2.7T1 pinout, X9250TS24-2.7T1 application, or X9250TS24-2.7T1 equivalent, this device is selected for low-noise, nonvolatile wiper position storage, <5µA standby current, and compatibility with 2.7V–5.5V digital supply while operating across ±2.7V analog rails - critical for industrial sensor conditioning and programmable gain stages.
Technical Context
The X9250TS24-2.7T1 implements four independent 255-segment resistor arrays, each controlled by an 8-bit volatile Wiper Counter Register (WCR) and four nonvolatile Data Registers (DR0–DR3). Wiper position is updated via SPI commands including direct write, register transfer, or real-time increment/decrement with SCK-synchronized edge control.
Its SPI interface complies with standard mode-0 timing (CPOL=0, CPHA=0), supports up to 2MHz clock frequency, and includes hardware write protection (WP), chip select (CS), and HOLD for serial transaction pausing. Analog operation requires separate V+, V− supplies referenced to VSS, enabling true bipolar signal handling across the full −2.7V to +5.5V range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total resistance | 100kΩ per potentiometer - defines maximum end-to-end impedance for voltage divider or current-limiting use. |
| Resolution | 256 taps (0.4% step size) - enables fine-grained analog adjustment with ±1 MI absolute linearity error. |
| Supply range | VCC = 2.7V to 5.5V; V+ = +2.7V to +5.5V; V− = −2.7V to −5.5V - supports single-supply digital logic and bipolar analog signal paths. |
| Standby current | <5µA total package - enables ultra-low-power operation during system sleep modes. |
| Nonvolatile endurance | 100,000 data changes per bit per register - ensures long-term reliability for field-updatable calibration settings. |
| Wiper resistance | 40Ω typical at VCC = 5V - minimizes insertion error in precision gain/offset circuits. |
| Temperature range | 0°C to +70°C - qualified for commercial-grade embedded instrumentation and test equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5242BRUZ100 | Single 256-tap 100kΩ pot; I²C interface; no bipolar analog supply support. | Limited to unipolar analog signals; requires external level shifters for ±V operation. | Select when only one channel is needed and I²C bus is preferred over SPI. |

FAQ
What is the supply voltage range for X9250TS24-2.7T1?
The X9250TS24-2.7T1 supports VCC = 2.7V to 5.5V for digital logic, and separate analog supplies V+ = +2.7V to +5.5V and V− = −2.7V to −5.5V. This enables true bipolar analog operation without level shifting. The "-2.7" suffix explicitly denotes the extended low-voltage analog rail capability, confirmed in the Ordering Information table on page 2 of FN8165 Rev.3.00.
How many potentiometers does X9250TS24-2.7T1 integrate, and what is their resistance value?
The X9250TS24-2.7T1 integrates four independent digitally controlled potentiometers, each with a nominal end-to-end resistance of 100kΩ. This is specified in the Ordering Information table (page 2) and confirmed in the Potentiometer Characteristics table (page 11) under "POTENTIOMETER ORGANIZATION (kΩ)" for part numbers ending in "TS".
Does X9250TS24-2.7T1 retain wiper settings after power loss?
Yes - the X9250TS24-2.7T1 stores wiper positions in nonvolatile Data Registers (DR0–DR3), with guaranteed 100-year data retention and 100,000 write cycles per bit. At power-up, DR0 automatically loads into the Wiper Counter Register (WCR), restoring the last-saved setting. This behavior is documented in the Device Description (page 4) and Endurance & Data Retention table (page 12).
What package type is used for X9250TS24-2.7T1?
X9250TS24-2.7T1 uses a 24-lead SOIC (Small Outline Integrated Circuit) package, 300 mil width, per JEDEC MS-013AC and package drawing M24.3. This is explicitly listed in the Ordering Information table (page 2) under "PACKAGE" for part number X9250TS24-2.7, and confirmed in the PIN CONFIGURATION diagram (page 3).
Can X9250TS24-2.7T1 operate with a single 3.3V supply?
Yes - X9250TS24-2.7T1 operates with VCC = 2.7V to 5.5V, so 3.3V is fully supported. However, analog operation requires both V+ and V− supplies: for unipolar use, V− can be tied to VSS (0V) and V+ to 3.3V; for bipolar use, V+ and V− must be set to symmetric rails (e.g., +3.3V/−3.3V), as defined in the Recommended Operating Conditions (page 11).
