Product details
Overview
X9241AUSIZ from Intersil is a quad digital controlled potentiometer (XDCP™) IC implementing four independent 64-tap nonvolatile resistor arrays with 2-wire I²C-compatible interface, ±3.0V to +5V terminal voltage range, and industrial temperature support (–40°C to +85°C), used for precision analog trimming in programmable power supplies and sensor calibration circuits.
For engineers reviewing the X9241AUSIZ datasheet, X9241AUSIZ pinout, X9241AUSIZ application, or X9241AUSIZ equivalent, this device delivers deterministic wiper positioning via volatile WCR and four nonvolatile data registers per pot, supports cascading of arrays up to 200kΩ, and enables fine-grained adjustment through increment/decrement command mode.
Technical Context
The X9241AUSIZ integrates four monolithic CMOS resistor arrays-each with 63 resistive segments and 64 tap points-controlled by dedicated 6-bit Wiper Counter Registers (WCR) and backed by four nonvolatile Data Registers (DR0–DR3) per pot. Each array operates as either a three-terminal potentiometer or two-terminal variable resistor.
It uses a standard 2-wire serial interface with slave address formed by fixed 0101b type identifier and user-configurable A0–A3 pins; supports global and individual register transfers; and implements cascade mode via CM bit (bit 7 of WCR) to link adjacent arrays electrically for extended resistance values.

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 with SPI interface, 256-tap resolution, no cascade mode, 2.7–5.5V supply | Requires SPI host interface; higher resolution but lacks I²C compatibility and array cascading | Select when SPI-native systems need finer granularity and lower supply voltage operation |
| MCP42050-I/P | Quad 50kΩ pot with SPI interface, 256-tap resolution, volatile-only memory, 2.7–5.5V supply | No nonvolatile storage; requires external EEPROM for power-up recall; no cascade functionality | Choose for cost-sensitive designs where configuration persistence is managed externally |
Compared with AD5204BRUZ10 and MCP42050-I/P, the X9241AUSIZ uniquely combines I²C compatibility, nonvolatile register storage with auto-recall, and hardware-enabled resistor array cascading - making it optimal for industrial analog reconfiguration where bus simplicity, configuration persistence, and extended resistance range are critical.

FAQ
What is the operating voltage range for the X9241AUSIZ potentiometer terminals?
The X9241AUSIZ supports terminal voltages from –3.0V to +5V referenced to VSS, enabling use in bipolar analog signal paths such as op-amp gain/offset adjustment and sensor bridge excitation. This range is independent of the 5V ±10% VCC supply requirement and must be observed to prevent damage to internal FET switches.
How does the X9241AUSIZ handle power-up wiper positioning?
The X9241AUSIZ automatically loads the contents of Data Register 0 (DR0) into the corresponding Wiper Counter Register (WCR) at power-up, ensuring repeatable initial wiper positions without host intervention. This behavior is hardwired and occurs regardless of prior WCR state or DR1–DR3 contents, making DR0 the designated "startup configuration" register for each potentiometer.
Can multiple X9241AUSIZ devices share the same I²C bus?
Yes - the X9241AUSIZ supports up to 16 devices on a single I²C bus using the A0–A3 address pins to configure unique 4-bit device addresses. Each device responds only to commands matching its physical address bits, allowing coordinated control of 64 independent potentiometer channels (16 × 4) with minimal GPIO overhead.
What is the maximum wiper current rating for the X9241AUSIZ at 50kΩ configuration?
At 50kΩ end-to-end resistance, the X9241AUSIZ supports a maximum wiper current of ±3mA. This limit applies across the full –40°C to +85°C temperature range and is derated linearly above 70°C per the DCP Wiper Current De-rating Curve in the datasheet. Exceeding this current risks irreversible degradation of switch FETs.
Does the X9241AUSIZ support true 4-wire (Kelvin) sensing for precision applications?
No - the X9241AUSIZ implements standard 3-terminal potentiometer topology (VH, VL, VW) with no dedicated sense terminals. Its 40–130 Ω wiper resistance and ±1% absolute linearity are optimized for general-purpose trimming, not metrology-grade measurements. For Kelvin sensing, external discrete resistors with separate force/sense routing are required.
