Product details
Overview
X9241AWSIZT1 from Intersil is a quad digital controlled potentiometer (XDCP™) IC integrating four independent 64-tap nonvolatile resistor arrays with 2-wire I²C-compatible interface, 10kΩ end-to-end resistance per pot, -40°C to +85°C industrial temperature range, and SOIC-20 package - used for precision analog gain/offset trimming in programmable power supplies and sensor signal conditioning circuits.
For engineers reviewing the X9241AWSIZT1 datasheet, X9241AWSIZT1 pinout, X9241AWSIZT1 application, or X9241AWSIZT1 equivalent, this page delivers verified electrical specs, wiper control timing, cascade mode operation, nonvolatile register behavior, and real-world design implications for embedded analog tuning systems.
Technical Context
The X9241AWSIZT1 implements four independent 63-segment resistor arrays, each controlled by a 6-bit volatile Wiper Counter Register (WCR) decoded to select one of 64 tap points. Each potentiometer includes four nonvolatile Data Registers (DR0–DR3) supporting direct read/write and transfer to WCR, with DR0 automatically loaded at power-up.
It operates via a bidirectional 2-wire bus (SCL/SDA) using I²C-compatible protocol with slave address formed by fixed 0101b prefix plus user-configurable A0–A3 pins. Cascade mode enables inter-pot linking (e.g., POT2→POT3) via CM bit in WCR, requiring external VH/RH–VL/RL connections and selective wiper disable (DW bit) for unified resistance scaling.
Key Specifications

FAQ
What is the exact end-to-end resistance value of each potentiometer in X9241AWSIZT1?
The X9241AWSIZT1 is configured with 10kΩ end-to-end resistance for all four potentiometers (Pot 0 through Pot 3), as specified in the Ordering Information table for part suffix "AWS". This value is factory-trimmed and holds within ±20% tolerance across temperature and lifetime, directly defining the analog scaling range in voltage divider or variable resistor applications.
Does X9241AWSIZT1 retain wiper position after power cycling?
Yes - the X9241AWSIZT1 automatically loads the contents of Data Register 0 (DR0) into the volatile Wiper Counter Register (WCR) on power-up. Since DR0 is nonvolatile with 100-year data retention, the last stored calibration value persists across power cycles without external intervention or MCU reinitialization.
Can X9241AWSIZT1 operate with a 3.3V I²C bus?
No - the X9241AWSIZT1 requires a 5V ±10% supply (4.5V–5.5V) and specifies VIH = 2.0V minimum and VIL = 0.8V maximum for address and clock inputs. While SDA/SCL logic thresholds are compatible with 3.3V signaling levels, the device itself must be powered from 5V; level-shifting is required if interfacing with a 3.3V microcontroller's I²C port.
How does cascade mode work in X9241AWSIZT1, and what external connections are needed?
In cascade mode, enabled by setting the CM bit in a WCR, two adjacent potentiometers (e.g., POT2 → POT3) are linked: VL/RL of the higher-order pot is connected to VH/RH of the lower-order pot. Only one wiper remains active (others disabled via DW bit), allowing unified resistance scaling - e.g., 20kΩ total from two 10kΩ arrays. External wiring must ensure continuity of all three terminals between cascaded units.
What is the maximum allowable voltage across any potentiometer terminal pair in X9241AWSIZT1?
The absolute maximum voltage difference |VH/RH – VL/RL| is 10V, and individual terminal voltages must remain within -3.0V to +5.0V relative to VSS. Exceeding these limits risks permanent damage to internal FET switches or resistor array elements, regardless of whether the device is powered or not.
