Product details
Overview
X9241AWS 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 10kΩ per potentiometer. It serves as digitally programmable analog gain/offset adjustment in precision sensor signal conditioning circuits.
For engineers reviewing the X9241AWS datasheet, X9241AWS pinout, X9241AWS application, or X9241AWS equivalent, this page delivers verified specifications, SOIC-20 package details, cascade-mode operation, wiper position persistence across power cycles, and real-world use cases in industrial calibration and audio level control.
Technical Context
The X9241AWS integrates four monolithic CMOS resistor arrays-each with 63 discrete segments and 64 tap points-controlled by individual volatile Wiper Counter Registers (WCR) and four nonvolatile Data Registers (DR0–DR3) per pot. Power-up automatically loads DR0 into each WCR.
It uses a standard 2-wire bus (SCL/SDA) with slave address formed by fixed 0101b type identifier plus user-configurable A0–A3 pins. All four pots share the same interface but support independent register access, global transfers, and cascaded array configuration via CM bit in WCR.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (A0–A3) | Address Inputs | Set LSBs of 8-bit I²C slave address (0101xxxxb); determine device selectability on shared bus. |
| 5 (SDA) | Serial Data | Bidirectional open-drain I²C data line; requires external pull-up; supports ACK polling and multi-master arbitration. |

| 7–10, 13–16 (VH0–VH3, VL0–VL3) | Pot Terminal Inputs | Fixed end terminals per potentiometer; VH/RH = high-side, VL/RL = low-side; support ±3.0V to +5V bias. |
| 11, 12, 17, 18 (VW0–VW3) | Wiper Outputs | Variable tap outputs per pot; electrically isolated when DW bit = 1; respond within 500µs after STOP. |
| 19 (VSS) | Ground | Digital and analog reference ground; must be connected before VCC during power-up sequencing. |
| 20 (VCC) | Supply | +5V ±10% supply; ramp rate 0.2–50 V/ms; must reach 90% before applying pot terminal voltages. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Potentiometer Integration | Four independent 10kΩ, 64-tap arrays reduce board space vs. discrete solutions and enable matched tracking in multi-channel systems. |
| Cascade Mode Support | CM bit enables linking adjacent arrays (e.g., POT2→POT3) to synthesize 4kΩ–200kΩ values without external resistors. |
| Nonvolatile Register Retention | DR0–DR3 retain wiper positions for ≥100 years with 100,000 write cycles-enabling factory calibration storage and field recalibration logs. |
| Increment/Decrement Command | Real-time fine-tuning via SCL pulses: HIGH = step toward VH/RH, LOW = step toward VL/RL-no host CPU overhead for manual adjustment. |
| Low Standby Current | 200–500 µA at VCC/VSS/Addr = standby state-suitable for battery-backed instrumentation and always-on sensor nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad digital potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5204BRUZ-10 | Quad 10kΩ pot; SPI interface; 256-tap resolution; ±5V supply; no cascade mode. | Requires SPI host interface; higher resolution but lacks I²C compatibility and array cascading capability. | Select when SPI infrastructure exists and finer 0.39% step resolution is needed over I²C convenience. |
| MCP42050-I/P | Quad 50kΩ pot; SPI interface; 256-tap; wiper resistance ~120Ω; no nonvolatile memory retention. | Needs external EEPROM for persistent settings; higher wiper resistance limits low-voltage signal fidelity. | Choose for cost-sensitive designs where external NV storage is acceptable and 50kΩ impedance matches circuit requirements. |
Compared with AD5204BRUZ-10 and MCP42050-I/P, the X9241AWS provides native I²C support, built-in 100-year nonvolatile storage, and hardware-enabled cascade mode-making it optimal for space-constrained, calibration-critical, and bus-shared industrial systems requiring zero external NV components.

FAQ
What is the exact resistance value and tolerance per potentiometer in the X9241AWS?
The X9241AWS is specified with 10kΩ end-to-end resistance per potentiometer (RTOTAL), as confirmed in the Ordering Information table for part marking "X9241AWS Z". Tolerance is not explicitly stated for this variant, but the base X9241A family supports ±20% RTOTAL variation per Analog Specifications table. Absolute linearity error is ±1 MI (±158.7Ω at 10kΩ), and ratiometric tempco is ±20 ppm/°C.
Does the X9241AWS retain wiper settings after power loss, and how is that implemented?
Yes, the X9241AWS retains wiper settings after power loss. Upon power-up, the contents of Data Register 0 (DR0) for each potentiometer are automatically loaded into its respective volatile Wiper Counter Register (WCR). DR0 is nonvolatile memory with 100-year data retention and 100,000 write cycles, ensuring factory or field calibration persists across all power cycles without external backup.
Can multiple X9241AWS devices share the same I²C bus, and how is addressing managed?
Yes, up to 16 X9241AWS devices can share one I²C bus. Each device uses the fixed 4-bit type identifier "0101" (binary) plus user-configurable address inputs A0–A3 to form a unique 8-bit slave address. The X9241AWS responds only when its A0–A3 state matches the last 4 bits of the transmitted address byte, enabling collision-free multi-device communication.
What is the maximum allowable voltage on the VH, VL, and VW pins of the X9241AWS?
The absolute maximum voltage on any VH/RH, VL/RL, or VW/RW pin is –3.0V to +5V referenced to VSS, as specified in the Absolute Maximum Ratings table. This allows bipolar signal handling (e.g., ±2.5V AC signals) and compatibility with dual-supply op-amps. Exceeding these limits risks latch-up or permanent damage, even if VCC remains within 5V ±10%.
How does cascade mode work on the X9241AWS, and what external connections are required?
Cascade mode links two adjacent potentiometer arrays (e.g., POT2 → POT3) by connecting VL/RL of the higher-order pot to VH/RH of the lower-order pot. Activation requires setting the CM bit (bit 7) in the target WCR to "1". Only one wiper remains enabled (DW = 0); others must be disabled (DW = 1) to float. Wiper movement then traverses both arrays seamlessly, synthesizing resistance values from 4kΩ to 200kΩ.
