Product details
Overview
X9241AWV from Intersil is a quad digital controlled potentiometer (XDCP™) IC with nonvolatile storage, 2-wire I²C-compatible interface, 64-tap resolution per channel, and 10kΩ end-to-end resistance per potentiometer. It operates from 5V ±10%, supports 0°C to +70°C industrial temperature range, and is packaged in a RoHS-compliant 20-lead TSSOP for precision analog trimming in embedded control systems.
For engineers reviewing the X9241AWV datasheet, X9241AWV pinout, X9241AWV application, or X9241AWV equivalent, this device delivers deterministic wiper positioning via volatile WCR and four nonvolatile data registers (DR0–DR3), cascade-capable resistor arrays, and EEPROM-like endurance (100,000 cycles) with 100-year data retention-critical for recalibration-critical instrumentation and factory-set parameter storage.
Technical Context
The X9241AWV integrates four independent 63-segment CMOS resistor arrays, each controlled by a 6-bit volatile Wiper Counter Register (WCR) and backed by four 8-bit nonvolatile Data Registers. Wiper position is set via direct WCR write, register transfer (e.g., DR0→WCR on power-up), or real-time increment/decrement commands over the 2-wire bus.
It implements full I²C slave protocol compliance-including start/stop detection, ACK polling during 10ms NV writes, and address decoding via A0–A3 pins-with SCL clock frequency up to 100kHz and absolute terminal voltage tolerance of –3.0V to +5V. Cascade mode enables series connection of adjacent arrays to achieve 4kΩ–200kΩ total resistance values.

| VW0–VW3 | Wiper outputs | Analog output nodes; electrically isolated when DW bit = 1; max wiper current = ±3mA (10kΩ) |
Key Features
| Feature | Design Value |
|---|---|
| Quad-pot integration | Four independent 10kΩ, 64-tap XDCP arrays reduce board space vs. discrete solutions and enable synchronized calibration |
| Nonvolatile wiper recall | Power-up automatically loads DR0 into WCR - ensures repeatable startup state without host initialization |
| Cascade mode | CM bit enables inter-pot cascading (e.g., POT2→POT3) to synthesize 20kΩ–200kΩ values using external wiring |
| Real-time wiper adjustment | Increment/decrement command allows host to step wiper one tap per SCL edge - ideal for closed-loop tuning |
| EEPROM-grade reliability | 100,000 NV write cycles and 100-year data retention meet long-life industrial equipment requirements |
| Low-power standby | 200–500µA VCC current in standby (SCL/SDA = VCC, Addr = VSS) - suitable for battery-backed systems |
Applications
| Laser Diode Bias Control | Programmable Gain Amplifier |
|---|---|
|
Use Scenario: Precise, stable bias current setting for telecom laser diodes requiring factory-trimmed thresholds and field recalibration. IC Role / Device Role / Timing Role: Four-channel analog trim element replacing mechanical pots; each pot sets current-limit threshold, modulation bias, monitor gain, and temperature compensation slope. Use Value: Nonvolatile DR0 recall ensures consistent laser turn-on behavior after power cycle; cascade mode extends dynamic range for high-current drivers. |
Use Scenario: Adjustable gain configuration in medical sensor signal chains where gain must be calibrated per channel and retained across power loss. IC Role / Device Role / Timing Role: Digitally programmable feedback resistor network; two pots configure differential gain, one sets offset null, one adjusts common-mode rejection. Use Value: 64-tap resolution provides <1.6% step accuracy; DR1–DR3 store alternate calibrations for multi-range operation without firmware update. |
| Industrial PLC Analog Output Module | Audio Channel Balance Control |
|
Use Scenario: 4–20mA transmitter calibration in programmable logic controller I/O modules requiring NIST-traceable zero/span adjustment. IC Role / Device Role / Timing Role: Quad potentiometer implementing precision current-loop setpoints: one for zero offset, one for span, two for HART communication impedance matching. Use Value: 100-year data retention guarantees calibration integrity over 10+ year product lifecycle; TSSOP package supports automated SMT assembly. |
Use Scenario: Stereo channel balance and tone control in professional audio mixers where mechanical pot wear and channel drift degrade performance. IC Role / Device Role / Timing Role: Dual-channel attenuation network; left/right pots implement balance; cascaded pots provide bass/treble shelving with matched tracking. Use Value: Wiper leakage <1µA prevents audible pop/click during adjustment; 120dBV noise floor preserves dynamic range in high-fidelity paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad digital potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5242BRUZ10 | Two independent 10kΩ pots (not quad); I²C interface; 256-tap resolution; 2.7–5.5V supply | Lacks fourth pot and cascade capability; requires two ICs to match X9241AWV channel count | Select if higher resolution (256-tap) and wider VCC range are prioritized over channel density and NV recall speed |
| MCP42010-I/SL | Dual 10kΩ pots; SPI interface; volatile-only memory; 2.7–5.5V supply; 256-tap resolution | No nonvolatile storage - wiper resets to mid-scale on power-up; incompatible bus protocol | Choose when SPI-native host architecture exists and recalibration at boot is acceptable |
Compared with AD5242BRUZ10 and MCP42010-I/SL, the X9241AWV uniquely delivers four independent nonvolatile pots in one TSSOP package with guaranteed power-up wiper recall from DR0 - eliminating post-boot host initialization and reducing BOM count in multi-channel analog systems.

FAQ
What is the exact end-to-end resistance value specified for X9241AWV?
The X9241AWV is configured with 10kΩ end-to-end resistance for all four potentiometers, as explicitly defined in the Ordering Information table for part number X9241AWVZ. This value is fixed per variant and not user-selectable; other variants (e.g., X9241AYVZ) specify 2kΩ, and X9241AUPZ specifies 50kΩ.
Does X9241AWV support true I²C bus compatibility including repeated START conditions?
Yes, the X9241AWV fully supports standard I²C protocol features: START/STOP condition detection, 7-bit slave addressing with A0–A3 pin configuration, ACK polling during nonvolatile writes, and repeated START handling with tSU:STA ≥4000ns and tHD:STA ≥4000ns timing compliance.
How does power-up wiper initialization work on X9241AWV?
On power-up, the X9241AWV automatically loads the contents of Data Register 0 (DR0) into the volatile Wiper Counter Register (WCR) for each potentiometer. This ensures deterministic wiper position without host intervention - provided DR0 was previously written with the desired startup value.
Can the four potentiometers on X9241AWV be cascaded, and what is required to enable it?
Yes, the X9241AWV supports cascading via the Cascade Mode (CM) bit in the WCR. Setting bit 7 of a WCR to '1' links that potentiometer's VL/RL to the next higher-order pot's VH/RH. External wiring and disabling all but one wiper (via DW bit) are mandatory; the resulting resistance is sum of individual RTOTAL values.
What is the maximum wiper current rating for X9241AWV at 10kΩ resistance?
The maximum wiper current for X9241AWV with 10kΩ end-to-end resistance is ±3mA, as specified in the Absolute Maximum Ratings table. This limit applies across the full operating temperature range and must be respected to avoid resistor array degradation or parametric shift.
