Product details
Overview
X9241AUVI from Intersil is a quad digital controlled potentiometer (XDCP™) IC with nonvolatile storage, 2-wire I²C interface, 64-tap resolution per channel, ±3.0V to +5V terminal voltage range, and -40°C to +85°C industrial temperature rating-used for precision analog trimming in programmable power supplies and sensor calibration circuits.
For engineers reviewing the X9241AUVI datasheet, X9241AUVI pinout, X9241AUVI application, or X9241AUVI equivalent, this page delivers verified electrical specs, TSSOP-20 package details, cascade-mode configuration guidance, wiper current limits, and real-world replacement options with documented functional differences.
Technical Context
The X9241AUVI implements four independent 63-element resistor arrays, each controlled by a volatile 6-bit Wiper Counter Register (WCR) and backed by four nonvolatile Data Registers (DR0–DR3). Each array supports three end-to-end resistance values (2kΩ, 10kΩ, 50kΩ), configurable per channel as listed in ordering data.
It uses a standard 2-wire I²C-compatible bus with slave address formed by fixed 0101b prefix plus A0–A3 inputs. Cascade mode enables inter-pot interconnection via CM bit control, while DW bit disables individual wipers for isolation-both functions validated in the instruction set and timing diagrams.

IC Role / Device Role / Timing Role: Dual-channel potentiometer operating in synchronous transfer mode (Global XFR) to ensure identical wiper positions across left/right channels. Use Value: 64-tap resolution provides ~0.5dB step size; cascade mode allows extended range for high-impedance line-level inputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar digital potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5242BRUZ10 | 2-channel, I²C, 10kΩ, 256-tap, no cascade mode, 100kΩ max wiper current | Lacks quad-channel integration and cascading; higher resolution but lower wiper voltage tolerance (±2.5V) | Select when higher tap count is prioritized over channel count and bipolar operation is not required. |
| MCP42010-I/P | Dual-channel, SPI interface, 10kΩ, 256-tap, no nonvolatile memory, 5V-only supply | Requires external EEPROM for power-up recall; incompatible bus protocol; no negative terminal voltage support | Choose for SPI-based systems where nonvolatility is handled externally and cost is constrained. |
Compared with X9241AUVI, AD5242BRUZ10 offers finer resolution but lacks quad integration and cascade capability, while MCP42010-I/P requires external memory and cannot operate with -3.0V terminals-making X9241AUVI uniquely suited for industrial bipolar analog trimming with self-contained NV storage.

FAQ
What is the exact resistance configuration of the X9241AUVI?
The X9241AUVI is configured as Pot 0 = 2kΩ, Pot 1 = 10kΩ, Pot 2 = 10kΩ, Pot 3 = 50kΩ, per the Ordering Information table in FN8164 Rev 7.00. This specific combination is fixed for the X9241AUVI variant and cannot be altered post-manufacture. Each resistor array maintains ±20% end-to-end resistance tolerance and ±300ppm/°C temperature coefficient.
Does the X9241AUVI support true bipolar operation?
Yes, the X9241AUVI supports true bipolar analog operation: its terminal voltage specification is -3.0V to +5V referenced to VSS, enabling use with signals spanning both positive and negative rails. This is confirmed in the Absolute Maximum Ratings and Analog Specifications sections of FN8164, and distinguishes it from many digital pots limited to unipolar 0–VCC operation.
How does cascade mode work on the X9241AUVI?
Cascade mode on the X9241AUVI is enabled by setting the CM bit (bit 7) of a Wiper Counter Register to "1", linking that potentiometer's array to the next higher-order one (e.g., setting CM in WCR2 cascades POT2 to POT3). External wiring must connect VL/RL of the higher-order pot to VH/RH of the lower-order one, and only one wiper remains enabled-verified in Figure 9 and Cascade Mode description on page 9 of FN8164.
What is the wiper current limit for each potentiometer in the X9241AUVI?
The X9241AUVI has differentiated wiper current limits: ±4mA maximum for the 2kΩ array (Pot 0), and ±3mA maximum for the 10kΩ and 50kΩ arrays (Pots 1–3), as specified in the Absolute Maximum Ratings table on page 10 of FN8164. These limits are derated over temperature and apply under continuous DC conditions.
Is the X9241AUVI pin-compatible with other X9241A variants?
Yes, all X9241A variants-including X9241AUVI-share identical 20-lead TSSOP pinout, pin functions, and electrical interface behavior. Differences are limited to resistance value assignment per channel, temperature grade (-40°C to +85°C for X9241AUVI), and marking; no PCB layout change is needed when substituting within the same package type.
