Product details
Overview
X9258US24IZ-2.7 from Renesas (formerly Intersil) is a quad digital potentiometer IC with 256-tap resolution per channel, dual ±2.7V to ±5.5V analog supplies, and 2-wire I²C-compatible interface. It integrates four independent 50kΩ resistor arrays, nonvolatile data registers, and volatile wiper counters-used for precision gain/offset trimming in industrial sensor signal conditioning, programmable filter tuning, and multi-channel DC bias control.
For engineers reviewing the X9258US24IZ-2.7 datasheet, X9258US24IZ-2.7 pinout, X9258US24IZ-2.7 application, or X9258US24IZ-2.7 equivalent, key selection criteria include its -40°C to +85°C industrial temperature range, 40Ω typical wiper resistance at ±5V, 5µA max standby current, and hardware write-protect (WP) pin for register integrity in field-deployed systems.
Technical Context
The X9258US24IZ-2.7 implements four independent 255-segment resistor arrays with CMOS switch-based wiper positioning controlled by an 8-bit volatile Wiper Counter Register (WCR). Each array supports three-terminal potentiometer or two-terminal variable resistor configurations via VH/RH, VL/RL, and VW/RW terminals.
Its 2-wire serial interface complies with standard I²C timing (400kHz max), supports 16-device bus addressing via A0–A3 pins, and enables nonvolatile storage of wiper positions in four 8-bit Data Registers per channel-with automatic DR0-to-WCR recall on power-up and hardware WP pin protection against accidental writes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Total Resistance | 50kΩ per potentiometer - sets full-scale voltage division ratio and current handling limit (50mW per channel) |
| Resolution | 256 taps (0.4% step size) - enables fine-grained analog adjustment with ±1 LSB absolute linearity error |
| Supply Range | VCC = 2.7V to 5.5V; V+ = +2.7V to +5.5V; V− = −2.7V to −5.5V - supports bipolar signal conditioning without level-shifting circuitry |
| Wiper Resistance | 40Ω typical at ±5V - minimizes insertion error in low-impedance feedback paths and attenuates high-frequency noise coupling |
| Standby Current | <5µA total package - enables always-on calibration storage in battery-backed instrumentation without significant drain |
| Data Retention | 100 years - ensures factory-trimmed settings persist across product lifetime without refresh circuitry |
| Endurance | 100,000 write cycles per register - supports field recalibration in maintenance-accessible equipment |
Pinout & Package
24-lead SOIC (300 mil, Pb-free, M24.3 package) with exposed pad not electrically connected. Pin 1 marked by notch or dot; pin numbering counterclockwise from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8, 11, 12, 13, 14 | Potentiometer terminals (VH0–VH3, VL0–VL3, VW0–VW3) | Direct connection points for analog signal path: VH/VL = fixed ends; VW = adjustable wiper output per channel |
| 9, 10, 15, 16, 17, 18, 19, 20 | Interface & control (SCL, SDA, A0–A3, WP) | SCL/SDA enable I²C communication; A0–A3 set slave address bits; WP disables nonvolatile writes when low |
| 21, 22, 23, 24 | Analog & system supplies (V+, V−, VCC, VSS) | V+/V− power analog section (±2.7V to ±5.5V); VCC powers digital logic (2.7V to 5.5V); VSS = system ground reference |
| NC | No connection | Pin 1 is NC - must remain unconnected to avoid parasitic coupling or latch-up risk |
Key Features
| Feature | Design Value |
|---|---|
| Quad independent DCPs | Four isolated 50kΩ, 256-tap resistor arrays allow simultaneous multi-channel calibration without crosstalk or shared register conflicts |
| Nonvolatile register storage | Four 8-bit DRs per channel retain wiper settings through power cycles - eliminates boot-time reinitialization in embedded controllers |
| Hardware write protection | WP pin assertion blocks all nonvolatile writes - prevents firmware glitches or ESD events from corrupting calibrated values |
| Bipolar analog supply support | Separate V+/V− rails enable true AC-coupled signal processing and rail-to-rail input/output swing in op-amp feedback networks |
| Low-power standby mode | 5µA max ICC in standby - suitable for energy-sensitive applications like portable test equipment and remote sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5204BRUZ10 | Quad 10kΩ pot, SPI interface, single 2.7–5.5V supply, no bipolar analog rails | Lacks V+/V− support - unsuitable for AC-coupled or true bipolar signal paths requiring independent analog supplies | Select when only unipolar operation is needed and SPI is preferred over I²C; verify 10kΩ impedance compatibility with existing feedback networks |
| MCP42050-I/SL | Quad 50kΩ pot, SPI interface, 2.7–5.5V supply, no separate V+/V−, 128-tap resolution | Halved resolution (128 vs. 256 taps) and missing bipolar capability reduce precision in high-dynamic-range sensor conditioning | Choose for cost-sensitive designs where 0.8% step size suffices and SPI infrastructure already exists; confirm layout accommodates SOIC-14 vs. SOIC-24 footprint |
Compared with AD5204BRUZ10 and MCP42050-I/SL, the X9258US24IZ-2.7 uniquely supports true bipolar analog operation with dedicated V+/V− rails and delivers twice the resolution-making it the only option among the three qualified for precision AC signal path trimming in industrial measurement systems.

FAQ
What is the operating temperature range for the X9258US24IZ-2.7?
The X9258US24IZ-2.7 is rated for -40°C to +85°C, qualifying it for industrial environments including factory automation controllers, outdoor sensor nodes, and power supply modules deployed in uncontrolled ambient conditions. This range is confirmed in the Ordering Information table on page 2 of FN8168 Rev 6.00, where "X9258US24IZ-2.7" explicitly lists "-40 to +85" under Temperature Range. The device meets this specification with all electrical parameters guaranteed across the full span.
Does the X9258US24IZ-2.7 support true bipolar analog operation?
Yes, the X9258US24IZ-2.7 supports true bipolar analog operation via dedicated V+ and V− supply pins, independently rated from -5.5V to -2.7V and +2.7V to +5.5V respectively. This allows direct interfacing with AC-coupled signals and op-amps operating on split rails. The datasheet confirms this on page 11 under "Operating Conditions" and "Analog Specifications", specifying separate V+ and V− limits distinct from VCC.
How many nonvolatile data registers does each potentiometer in the X9258US24IZ-2.7 have?
Each of the four potentiometers in the X9258US24IZ-2.7 has four nonvolatile 8-bit Data Registers (DR0–DR3), totaling sixteen registers. DR0 is automatically loaded into the Wiper Counter Register (WCR) on power-up. This architecture is detailed on page 1 of the datasheet ("four non-volatile Data Registers (DR0:DR3)") and elaborated in the Register Descriptions section on page 8.
What is the maximum clock frequency supported by the 2-wire interface of the X9258US24IZ-2.7?
The X9258US24IZ-2.7 supports a maximum 2-wire (I²C-compatible) clock frequency of 400kHz, as specified in the "AC Timing" table on page 13 of FN8168 Rev 6.00. This allows efficient register access in real-time control loops while maintaining compatibility with standard microcontroller I²C peripherals operating in fast-mode.
Is hardware write protection available on the X9258US24IZ-2.7?
Yes, the X9258US24IZ-2.7 includes a dedicated hardware Write Protect (WP) pin (Pin 20). When pulled low, WP disables all nonvolatile writes to the Data Registers, preventing accidental corruption of calibrated values during system operation or firmware updates. This function is documented in the Pin Descriptions section on page 3 and the Principles of Operation on page 4.
